Forces Posted May 19, 2007 Share Posted May 19, 2007 I am sure some of you have tried wrapping block huggers with a JTR set back position. The thing that I ma debating is weather or not you can actuall fit the wrap on? The header- steering shaft clearance is very tight, and it seemes that if they touched one another, it would tear the wrap up. Also.... is there a way to tell weather or not headers are ceramic coated? I ordered a pair of coated summit brand block huggers for angled plug heads. My under hood temps are very high, and a part of me thinks that I got F***ed by Summit and they sent me a non-cearamic coated product.

piston Posted May 19, 2007 Share Posted May 19, 2007 ceramic coated looks like aluminum...it will be a tight fit with the huggers wraped. depending on wraping skills, ive seen nice tight wraps to ugly loose wraps...the wrap is not going to tear up and you dont need to wrap in between, just wrap all the bottom runners together...

e_racer1999 Posted May 19, 2007 Share Posted May 19, 2007 is it just a myth that headers deteriorate faster with wrap because of the temps reached? Quote Link to comment Share on other sites More sharing options...
DavyZ Posted May 19, 2007 Share Posted May 19, 2007 Forces, if they look like they are ceramic coated, they probably are. I don't think Summit intentionally screws people by sending them silver painted headers. Has their customer service slipped that much? Anyway, about the header wrap. dmanzo57 on this site has his block huggers wrapped. I can't find a picture at the moment, but he wrapped the majority of the headers as I recall. I'm sure allowances have to be made when you get to the parts that are very close together. Maybe Don has a pic or two. I'll look. You can also email or PM him--just search for his member name.

Chemicalblue Posted May 19, 2007 Share Posted May 19, 2007 I thought the silver looking ceramic coating was for repelling/expelling heat and the black ceramic coating was for heat retention. Are they done inside and out? I had my intake mani done in silver and exhaust in the black and I noticed a big difference. Quote Link to comment Share on other sites More sharing options...
280Zone Posted May 19, 2007 Share Posted May 19, 2007 e racer, I think headers deteriorate faster when wrapped if they are bare steel since they retain moisture and promote rust. Mostly when the car isn't being driven and they are not hot. Quote Link to comment Share on other sites More sharing options...
David K Posted May 19, 2007 Share Posted May 19, 2007 Its true they rust out quicker. Just ask Pallnet about his friend Chris's header (evil inside). Quote Link to comment Share on other sites More sharing options...
piston Posted May 19, 2007 Share Posted May 19, 2007 if you wrap ceramic coated headers, the wrap will almost melt itself onto the header and cause the wrap to stick to the headers but i guess thats what they are suppose to do anyways....i had some wrap on my old honda dc headers and it seems like it kinda melted onto the coat...i think it might have tiny micro fiberglass strands in it..im sure it does the same for others too but i could be wrong. by the way, what engine is that in the pic above, i thought it was an lt1 but its not..looks like a mix and match motor with older sbc valve covers with wierd looking lt1 manifold. it looks like it has an lt1 elbow and throttle body but the water pump looks like an older gen...

steal my nametag Posted May 19, 2007 Share Posted May 19, 2007 it looks alot like the TPI engine but i'm not 100% it's either that or an early gen conversion... it reaaaaaaaaaaaally looks like an upgraded TPI though.. not chevy's best factory endevour IMO.

DavyZ Posted May 21, 2007 Share Posted May 21, 2007 It's no TPI. I believe Don's car has a Miniram, but I'm not exactly sure. However, I am sure that 1) it's aftermarket and in no way stock and 2) it's programmable FI that brought him into the very very low 11's in the 1/4 mi with the 383 Gen 1 motor you see there. Simple JTR + aftermarket efi = very effective. It's the smoothest and fastest Z's I have driven to date. No bugs in that one--he's used it as a daily driver for years although now, with gas at over $3.50/gal, I'm not sure anymore. Davy Quote Link to comment Share on other sites More sharing options...
Savage42 Posted May 21, 2007 Share Posted May 21, 2007 is it just a myth that headers deteriorate faster with wrap because of the temps reached? No myth. Header wraps will kill your headers much sooner than without it. It keeps extreme heat inside and will eat away material over time. A friend of mine wrapped his exhaust manifold and about 2 years later, took the manifold off, dropped it and it broke in a couple pieces. Also kills cast iron!! Ceramic coating is the way to go, as you get a layer inside and outside of the metal. Quote Link to comment Share on other sites More sharing options...

Forces Posted May 24, 2007 Author Share Posted May 24, 2007 I'd like to get back to what ChemicalBlue was saying about the color differences. All of the ceramic coated headers I have ever seen for sale through a commercial copmany (i.e. Hooker, headman, sanderson, etc) have been silver coated, however My buddy got his headers coated is some run-down shack that were done in flat black. Is there really a difference in heat containment with different collors of coating? It doesn't seem to me that color alone would make a difference, as engine heat is not a product of a light source. Anyhow, thanks for the pics and info, very helpful. Quote Link to comment Share on other sites More sharing options...
DavyZ Posted May 24, 2007 Share Posted May 24, 2007 ...All of the ceramic coated headers I have ever seen for sale through a commercial company (i.e. Hooker, headman, sanderson, etc) have been silver coated, however My buddy got his headers coated is some run-down shack that were done in flat black... Hmmm, the general marketing of "ceramic coated" headers is for a bright finish. I would think flat black would be suspect. Are your headers flat black like your buddy's? Summit sent you them and they should describe them. If you have flat black ones, I'd call them up and discuss your order. I think their customer service is great, just don't start yelling and they should be receptive. Davy Quote Link to comment Share on other sites More sharing options...
Forces Posted May 24, 2007 Author Share Posted May 24, 2007 No, I didn't mean to say that MY headers are black, they have a typical aluminum finish, as described above. I was just inquiring on the efficacy of using different colors (types?) of ceramic coating. Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted May 24, 2007 Share Posted May 24, 2007 Header wrap absorbs moisture holding it against the hot headers. An absolute receipe for rust. Ceramic coat is like a high quality paint that keeps moisture and air away from the raw steel. Quote Link to comment Share on other sites More sharing options...

pparaska Posted May 25, 2007 Share Posted May 25, 2007 The higher temperature capable coatings are usually not silver but black, blue or grey: http://techlinecoatings.com/BulkExhaust.htm http://www.jet-hot.com/Pages/coatings.html (see the 2000 coating) Quote Link to comment Share on other sites More sharing options...
