Stock LT4 Heads

If i put 2.02 valves in the stock LT4 heads, will I pickup any additional HP with a LT4 Hot Cam with the regular LT1 engine(1995 Camaro Z28 A4). If so, how much more power?

I wouldn't change the stock LT4 valves. They are specially designed and are hollow on both intake and exhaust, with the exhaust valves being sodium and potassium filled to help dissipate heat. Besides which, they are already 2.00 intake and 1.55 exhaust. I wouldn't expect you to gain ANY noticeable HP, and you might even loose some due to heavier valves.
