How much seat pressure for a 2.02 valve and a XE grind cam I'm just setting up my springs (Crane Duals with stripes) on my ported heads. I was wondering what kind of seat pressure is needed for a aftermarket 2.02 valve( not sure of the brand ) with a Comp XE grind. The specs on the cam are 228/230 .571/.573 on a 112. I'm hoping people with these springs can tune in. I believe Paul at Thunder recomended 145 at the seat with stock heads and valves. Thanks!

Stock rockers etc, I'm measuring seat pressure with installed height. My cranes on my AS heads were set up at 1.8 and they started to float-seat pressure was only 112. I went wth a 1.71 installed height and 140-150lbs. Thanks for the compliment.
