i have a set of 5.3s that are being p&p is it worth the cost to go to the 2.02 valves on the intake side? i have a stock 2.00 in my ls1 heads i was going to go to just the 2.00 but what hp number would i really look at going to the 2.02s vs 2.00?

 

You'll be looking at average 5cfm improvement

 

im gonna say its not worth the money to spend buying all new valves and seats when i have the stock 2.00s on hand already correct?

 

anyone ? need to know before the machine shop

 

i went with 2.00", my machinist said the 2.02 would be cutting the seats awfully thin.
