tailgatewagon Posted June 4, 2006 Share Posted June 4, 2006 just wondering, everyone talkes about decking the head on ea cars to raise the compresions.... why not deck the motor and leave the head alone the reason being to keep the head material as thick as possilbe.. anyway just a thought...

[HTi]Johnson Posted June 4, 2006 Share Posted June 4, 2006 I the reason is... it's easier to deck the heads, to deck the block, you'd more than likely have to split it. Gotta be carefull. Decking the heads and/or block, could make the intake not bolt on anymore (I'd think after some serious metal was removed). Oh, maybe they deck the heads mainly due to warping?

SOOBOUTLAW Posted June 4, 2006 Share Posted June 4, 2006 Aluminum heads tend to warp, but the block doesn't seem to. It's weird. Quote Link to comment Share on other sites More sharing options...

Hi tailgatewagon, I've decked a block to make it square with the world but...piston to cylinder head clearance is the first thought that comes to mind. How little you can get away with is something i just don't know at this point. I'll be finding out tho. Somewhere down the line.

All_talk Posted June 5, 2006 Share Posted June 5, 2006 In general, 0.030 is the standard for deck clearance, so depending on compressed head gasket thickness some piston hight above the block may be fine, I know the EJ22T has some. Be sure to check for valve clearance. Gary Quote Link to comment Share on other sites More sharing options...
