Anyone know what size valves TEA uses on their LS1 Stage 2 port job?

Thanks,
John

2.02/1.57

stage 1.5's use a 2.02 intake valve and a stock exhaust valve.

its no difference hardly in the flow numbers on the stage 1.5's and 2's

they both peak around 299-306 on the intake at 600

only difference is the valves and supposedly the stage 2's have stronger valves for n20 and boost perhaps

Yeah, the Stage 1.5's use the stock exhaust valve, and believe it or not, they outflow the aftermarket valve. Not by much though, maybe 8-10 cfm's up top.

The stock exhaust valve actually loves nitrous, it's just the boosted applications where you want to be careful.
