I know this will probably be frowned upon, but I suggest you read this link...TONS of good information. Once you are done reading it, read it again.

Good luck.

 

Injuneer come on man will you just tell me if the 2.02/1.6 will work in the stock chamber head or not? thats all i want to know

 

It was mentioned to you in the 4th post that without new seats 2.00"/1.56" is as big as you can go. If you have the seats changed you can run the 2.02"/1.6"s, although I'd strongly recommend using stock-sized valves.

 

New seats are probably at least $10 apiece times 16 valves, so using the wrong sized valves is not such a good deal.

As I said Comp's rpm ranges are all wrong for the LT1. I run a cam with less duration than that and it peaks about 6400.

You want an off the shelf Comp cam look at the 503.

If your heads turn out well this may actually still be best to take to 64-6500, if they are average you will get by with 6300. Basically you can plan on Comps LT1 RPM ranges being off a good 10%+ as they rate this one to just 5800
