Valve Diameter Questions
I have some questions regarding valve diameters...
What does it mean
5.3 heads are Intake is 1.89" and Exhaust is 1.55"
LS1 heads are Intake is 2.00" and Exhaust is 1.55"
LS1: intake = 101 grams, exhaust = 94 grams.
LS6 heads are Intake is 2.00" and Exhaust is 1.55". But the
LS6: intake = 73 grams, exhaust = 65 grams
I am looking for a good head to go with my 228/232 .588/.595 110+4 cam. And in the near future a FAST 90/90 combo..
Thanks guys

jonas get get caught up into the valves too much...light weight valves are nice but not going to give you huge gains, especially only spinning it to 6600 (i think that is what you said you shift at)...
also 5.3 heads with a stg 2 port job use stock 2.00 valve...now if you go to a stage 2.5 you get the 2.02 valve...
