Jwink25 Posted June 18, 2003 Share Posted June 18, 2003 Getting my Turbo head rebuilt. Is there anything I can have them do to add a few more HP...without having to pay to much more? (as if HP is ever cheap! ) I am gasket matching the ports myself. They are doing a valve job, cleaning, and checking the head, ect. Thanks, Jason Quote Link to comment Share on other sites More sharing options...
Guest JAMIE T Posted June 18, 2003 Share Posted June 18, 2003 I've not ever taken a L-series haed apart, but, most power is found under the valve. Or, "the pocket", or, "Bowl" as it is sometimes called. When I port a set of heads, I usually spend the most time in that area. Streamline the valve guides to a tear drop shape. open the bowl up so that there are no abrupt turns. Smooth out the short side radius. Hope this helps.

Guest Zcarsmakemyheadhurt Posted June 18, 2003 Share Posted June 18, 2003 Match port the intake.... Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted June 18, 2003 Share Posted June 18, 2003 My head builder did some valve unshrouding around the exhaust valve. Quote Link to comment Share on other sites More sharing options...
ratedZ Posted June 18, 2003 Share Posted June 18, 2003 How much did it set you back? I have to do this to mine as well and just trying to get a feel of how much $$$ I will have to spend. Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted June 18, 2003 Share Posted June 18, 2003 I got charged a good amount. I got rolled for new turbo rockers, and I sprung for a new cam and valve springs (Schneider turbo cam, single spring). New lash pads, reground the valves and seats, new guides and seals (I believe), resurfaced the head, and just the minor valve unshrouding work set me back about $1500.

Jwink25 Posted June 18, 2003 Author Share Posted June 18, 2003 It is costing me only $110. They are tearing it apart, cleaning it, doing a valve job, checking the deck surface, milling it if needed, everything short of replacing valves, cam, and springs. Having a crack in the front timing chain area fixed as well; for an extra $60. The head came off a low milage car that was wrecked. So it doesn't really need anything other than that small crack fixed. It's just that while it is in the shop getting toren apart, to be cleaned, and have the crack fixed...might as well have them check the rest of the head, and get a valve job. I am having them give me the head after its been disassembled so I can do some mild porting myself. I'll gasket match too. Hope I don't screw it up, Jason Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted June 19, 2003 Share Posted June 19, 2003 Good port work is expensive. Don't get to happy with the grinder either, you can do more damage then good. If you do decide to port it, send to to someone who has done L6 heads, and who has a flow bench. Quote Link to comment Share on other sites More sharing options...
Jwink25 Posted June 19, 2003 Author Share Posted June 19, 2003 Could I just smooth things out a bit? Kinda just polish it, instead of removing much metal? Will that gain me anything on a turbo head? Thanks, Jason Quote Link to comment Share on other sites More sharing options...

Thanks, Jason[/quote'] Personally, I wouldn't touch it. The ports already match the gasket, it's the intake that needs grinding to match. You won't make much, if any noticeable improvement, and you risk making it worse. But that's just my opinion. Quote Link to comment Share on other sites More sharing options...
Jwink25 Posted June 19, 2003 Author Share Posted June 19, 2003 So, the exhaust side is ok then? Is there anything that needs to be removed there? It looked to me that maybe the exhaust ports could be enlargened some? I'll take another look at it when I get it back tomorrow . thanks, Jason Quote Link to comment Share on other sites More sharing options...
