Re: 5.3L or 5.7L stgII heads....which would be better? Ron, where are you getting the info that 5.3 head exhaust port outflows 5.7? I am unaware of this, smaller chamber of 5.3 hinders flow overall(even relieved). Max effort 5.7 intake flows slightly more than 5.3 also.

Re: 5.3L or 5.7L stgII heads....which would be better? Check out TEA's website and they have flow comparisons for the 5.7 and 5.3's.

Re: 5.3L or 5.7L stgII heads....which would be better? The 5.3's do flow more air on the exhaust side than the 5.7 everytime, given they have the same valve, most of the time a 1.6 valve in a 5.7 won't flow as much as a 1.55 in a 5.3 head.
