Hi I got 97 LT1 Camaro M6 trans and I built a strong 383 LT4 Block.. I will spray 150-200 wet shot.. The question is which heads should I use.. This is my daily car, some times in traffic.. 210cc or 195 cc??

After a few months I will probabily go with supercharger and I want to use the same heads off course..

Camshaft selection will change related to how big will the heads right?? My injectors are 30 lb..

any suggestion will be great..
thanks

210cc. i had the 195s on my 406sb and i loved them but i would definatley rather have the 210cc

WhtLT1

I would say the 210's at first NA they might not be the best for velocity. But once u spray it or go FI they should be just wat youo are looking for

Also on AFR web site they suggested 76cc combustion chamber for 210cc heads .. But the compression will be 11:1 so I will go with 64cc combustion chamber .. Its true??

What type of pistons do you have? To achieve a 11:1 CR with a 64cc chamber, you will need the equivalent of a 6cc dish on your pistons with a .040" thick head gasket. With the same gasket, a 76cc chamber will call for a 6cc dome to get the same CR.

We just got our 210s in and they spec'd out at 199cc... Needless to say they were sent right off to ported correctly

My pistons are Diamond forged -5cc relief 0.30" .. With 210cc heads should I go with 0.40" pistons???

With 210cc Heads 0.30" is fine??
