DspecDJ Posted January 14, 2007 Share Posted January 14, 2007 So I'm about to get into doing some head porting work at school and I'd really like to get my hands on a spare head for my 240Z and do the work on that so I have something I can use when I'm done, I'm looking to do a just a mild port and polish job, just something to focus on streetable power increase, I'll probably back-cut the valves while I'm at it because I had a friend with a VW 8v and he back-cut his valves and saw an 8% increase in flow from that alone. So pretty much my question is for anyone who has experience with doing this kind of work on these heads, any areas I should particularly focus on? Any spots that need special attention? If you can post pics up please because I have not seen these heads off the engine yet (I'm still looking for a decent project head) Quote Link to comment Share on other sites More sharing options...
Administrators BRAAP Posted January 15, 2007 Administrators Share Posted January 15, 2007 Hmmm.. Apparently you didn’t use this sites “SEARCH” function. This forum has pretty much every bit of detailed information including detailed pics, that you could possibly want for custom building an L-series head. From cutting the valve seats with 5 angles, back cutting the valve’s themselves, setting up high performance valve trains, and LOTs of pics and text regarding porting, chamber reshaping, valve unshrouding etc… Start here at this links below and perform a search. Pretty much EVERYTHING you would want to know about L-series head work is here! Custom L-head work and what’s involved… http://forums.hybridz.org/showthread.php?t=108398 Custom P-90a http://forums.hybridz.org/showthread.php?t=113246 Big and Nasty head work… http://forums.hybridz.org/showthread.php?t=104420 Quote Link to comment Share on other sites More sharing options...

vashonz Posted January 15, 2007 Share Posted January 15, 2007 I've got a couple extra E88 head and an E31 head sitting around. I can get some phoots of one of the E88s if you want, The E31 is still on the engine. This reminds me to break down those engines and pull the 9mm rods. (any other parts I should pull?)
