Thinking about some heads Just looking for opinions. Thinking again about going heads and cam. I've narrowed my choices to these two.
MTI stage 2E or TEA stage 2 both 5.7 LS1 castings.
Also, I've noticed A lot of guys seem to be running 5.3 castings. Whats the benefit in this?
Thanks to all

Thats what I thought, do they flow much/ifany worse than a 5.7L casting?
Check my sig GMPP LS6 heads are unbeatable for the price. They make badass power. These heads don't just make the advertised peak number people like to brag about, it's the killer flow through out the 500's also.

Ya those do look pretty nice, a bit more pricey than either the MTI or TEA's at about $2k for the pair.I assume one would want to upgrade the springs though as they are the stock '02 ZO6 springs.

All else being stock? Do you think I would I be able to hope for close to the same numbers with an otherwise stock setup and a slightly more aggressive cam(no idea which yet, haven't even begun researching that)

Just checking.

Nope, I am also running the GMPP LS6 heads. They are an incredible head. I had them independently flowed on flowbench(no exhaust tube), and they flow every bit what they advertise. Remember, these are stock valves that are outperforming some big name heads where it counts the most....the mid lift numbers. Peak cfm is worth nothing more than bench racing. If you wanna go fast, it's all about the low/mid range numbers.
correct me if im wrong.....but dont Summitt racing have GMPP LS6 heads for about 1450.00......Cause that was what i was looking into getting????? After all the whole LS1 to LS6 conversion for 01-02 cars is like only 1799.00.........what gives with these 1800.00 to 1900.00 dollar heads???????????
My car is a 99. Its a different bore size. I understand the head flows great but what about the fact that the combustion chamber is larger than my bore size. What is the effect there is the question?
