Zo6 Heads
#3
I'm not sure. I'm new to the LS1 world. Ever since I've owned my car which is only about six months I've been amazed about how many options there is out there to an LS1 they have what a LS2 and a 6. What is the difference on all these besides the years of the motor? What parts can you interchange and what can't you? Like I said the add said Z06 heads $500 dollars are. I have a 99 TA all stock. Are they even worth buying our should I get something aftermarket like Trick Flow. What is the difference between my stock ones and the stock Z06 or LS6 heads. Horsepower rating that is.

if you're bone stock, there are better things to spend your $500 on.
lie, intake, headers, exhaust, gears, shifter, torque converter, suspension....depending on what your car is...
the ls6 heads are what came on the zo6 optioned corvettes. they are slightly higher compression i think and flow a little better than the ls1 heads. stock for stock on a bone stock motor you'd probably see about 10hp. not enough to make it worth it.
however they can be ported by any one of sponsors to be a really great flowing set of heads. mate that with a cam and you can have some serious power. but it depends on your goals and wallet.
for comparison,
ls1 heads flow ~240cfm i think
ls6 heads flow ~260cfm i think
ported heads generally average around 290-310cfm
