Piston clerance

[TOYJOETA]

     I have an 85" 22re and did a head gasket and timing chain on it.  When I put the timing cover back on I f'ed up the part of the head gasket that seals the top of the cover and now has a nasty oil leak that is pissing me off.  So I want to do the head gasket again the Question I have is how much can i shave the head with out worrying about piston clerance.  I have 2mm bigger Intake and exhast valves with a TRD stage 2 cam.  I just would like to gain a little more Compression. I live in Colorado so any little bit will help.

Thanks
Joe.

you could shave .005"  with no problems maybe more,  what lift and duration at .050 does your cam have???

i havent played much with the efi blocks,   but i think im going to pic one up to experiment with

     I can't remember the specs on the cam I'll have to look for the cam card some time.  I think it is a dual gind cam.  If I take .005" off what would that raise the compression to?  Also do you know which plenum is better the early 85-92 or the 93-95.  I would like to clean up some of the vacuum lines, I read the board on that in the pirate forum but would still like to know more.

.005 isnt going to raise compression much,  like i said im not as familiar with the efi blocks or vacuum hose needs,   my hybrid had about 3 vacuum hoses on it,  including brake booster


i would stay with the early plenum,  go to LCEngineering.com
