I have never run over 135 seat pressure on a hyd. roller cam.
What are your thoughts on 150 seat pressure on a hyd. roller cam ???

run 140/150 on seat and a rev kit on the lifters that the only way i would go them ss valves are not lite and the boost???i run all the hp roller cams at 140lbs i would all so add them lifters are going to hop if you can not keep them on the cam they are very heavy that is why i would add the rev kit. no way would i think of not running one on a build like this
