So I got my Crower regrinds. Took longer then I wanted so I have not been on the forum for a while. It looks like on the intake the base circle is 1.500 and then they grinder it down to 1.350. I had them keep both intake and exhaust under 10mm lift. They gave me .085 shims for the intake. It's weird though when the cams are installed and locked in place I can pore liquid in the intake port and it comes out the exhaust? Is it possible the lifters can spring open just sitting. I didn't have any shims at all on the exhaust so I can't even explain how that valve would be open.

u can have a lifter problema!!!!
u´re using the hyd lifters or u changed to mech tappets?
if the valves are opened something is making them open, or they dont seal properly, can be that as well.

Lifters pump up all the time when you mess w/the motor. Have you never started a motor that sounded like no compression and missed for a while than smoothed out? That's lifters.

You were correct Raysorenson. They sat overnight and everything sealed up nice!
