WS6tech any 403 boys know the answer??

WS6tech thansk guys frot he mailing address. I searched all posts with "403." It seems as if a lot of people here know what they are talking about. I just can't understand how chevy can have flat-tops with 64cc chambers. I do realize the head designs may be different though.....So basically, has anyone here run flat tops on their 403(not with 83cc smog head). IF it won't work, I'll get some forged dished...

WS6tech I have to run dished in Olds 350 heads??? I had no idea. Would the compression just go through the roof if I went flat top???? If I stay dished, I'll just wire wheel and clean the dished pistons I have now....
11-20-2002 07:28 PM if you put flat top pistons in an olds you will probably have to run it as a diesel, seriously the chambers in the olds are small so you have to run a dish piston.
