So, I'm fixing all the leaks on my Chebby Cumaro (so I can sell it and finish the foxbody) and I have the intake off, and I heard that the heads were ported. Well, what kind of port job is this? Looks like someone took a die grinder and hit the out side of the ports. The sad part is the previous owner paid a lot of money for this port job. The exause side was never touched. Stock LT1 heads flow 212cfm on the intake side, so I guess these flow 214.
