What heads, cam, and valve springs are you running on your combo? Len, I'm with you. I'm way too old to live that close to a sudden sharp pain in the area of my wallet pocket. :)
I'm running a 'Scott Brown' flat solid about .575 lift and 265 degree duration @.050". Pretty unremarkable. Dual springs sent with the cam (read no name). Think Scott said they have 150lbs. seat and 380 open. The heads are econno W2's ported by me.
