Here is a link to an LT1 head flow chart. It shows stock heads vs aftermarket heads.

Hey Bob thanks for that awesome chart. I noticed you said "good luck with your project". You musta seen all my other posts on porting my own heads huh. I'm debating if I should get them flowed. In a way I don't want to because if they are crappy I'll kick myself.

DAMN BOB......YOU GOT ONE KICKA$$ CAR!!! .
How much you got invested in that?????? SAWEEEEET

I spent way too much on this car. One place where I spent a lot of money is on heads. I got the CNC Machine CNC ported heads that flow well. An engine cannot run if it cannot breathe.

On our bench, the 92-95 castings peak in the 210-212 range on the intake and 163ish on the exhaust.
