LS6 heads can withstand more abuse than the ls1 heads. Do it.

New 243s here. How much should I mill them? Going with a TR224 I think.

IMO all ls6 heads are is a tuned up pair of ls1 heads. The difference in cfms are minimal. Anytime you port and angle heads and valve you should mill (0.30) the heads this will pump up compression and somewhat insure a good seal. If you have ls1 heads be sure to grab an ls1 intake.

Would milling and putting a thinner gasket be the same thing?
