deMideon Posted March 12, 2002 Share Posted March 12, 2002 As I have never been into SBCs before I have never had this come up. So... I wanted to find out which I should go with... angle plugs or straight plugs. What are the drawbacks of each, what are the benefits? Thanks!!!

John Scott Posted March 13, 2002 Share Posted March 13, 2002 As far as the Z is concerned the straight plug heads usually offer more clearance to your headers than angle. JS Quote Link to comment Share on other sites More sharing options...
V8ZRACER260Z Posted March 13, 2002 Share Posted March 13, 2002 I am using 215cc Dart Iron Eagles with straight plugs. Make sure you check your headers for proper clearances also. I still had to clearance the inner pipes to clear the plugs. Alot of the aftermarket heads have relocated plugs for better performance. Check with the head manufacturer for header recomendations.

John Scott Posted March 14, 2002 Share Posted March 14, 2002 Some header manufacturers make headers for angle plugs. The most common header for the Z swap, block hugger hookers, offer more room with the straight plug. Might depend on head type, too.

deMideon Posted March 14, 2002 Author Share Posted March 14, 2002 Really! I would have thought angled would be better... I'm glad I asked. How hard is it to get them in or out. Does it make a difference? Thanks!!! Quote Link to comment Share on other sites More sharing options...
DavyZ Posted March 14, 2002 Share Posted March 14, 2002 I think it was BLKMGK or someone else that has angled plugs--ran into a few problems with header clearance. (I could be wrong about this, but a search will reveal more info). Also, I know there are at least two guys on the forum that run angled plug heads with no issues. It really depends on the header to head compatability. FWIW, I have straight plugs and I have at least 1/8 inch clearance between the thick plug wire boot and the header itself--no burned wires for me!!

Guest zfan Posted March 14, 2002 Share Posted March 14, 2002 I used to run angle plug double hump heads. Found that Sanderson made headers that fit the Z with those heads. zfan..Mike Quote Link to comment Share on other sites More sharing options...
nullbound Posted March 14, 2002 Share Posted March 14, 2002 i had a 350 in my car with straight plug tuned-port 305 heads. i used hooker block huggers with that setup. in december, i replaced that engine with a 377, using canfield heads (angled-plugs). the hooker block huggers would not work with my heads. i had posted a question on here about what headers to use with angled plugs, and was pointed here: http://www.zigsstreetrods.com/engparts/headers.htm the rw37's are the ones that i use. great price AND they come coated. i get plenty of clearance, too, between the sparkplug wire boots and the headers. i may change to full length headers in the future. the S&S headers full length will work with angled-plugs, too.

labrat Posted March 14, 2002 Share Posted March 14, 2002 The way those rw37's tubes are reversed, they just might be the header for me to clear my power steering gearbox on my 81 ZX... Quote Link to comment Share on other sites More sharing options...
