Silly me, I was going to have the spring seats machined. I took my heads to my machinist to have them machined and walked out with a set of +.050 valve locks. I'll put them on the exhaust valves only.

I would say that only the designer of the cam profiles can correctly answer the spring force [not "pressure"} questions. Values such as peak negative acceleration aren't usually available to end users.

The designer of the cam is gone now but, Bullet knows Ultraydyne cams as well an anybody . Tim at Bullet worked for Harold for several years. Bullet highly recommended to run 1.65 and they recommended the springs too.

Yeah I already check the clearance and it's good. My machinist made the same recommendation. Thanks
