oh, and i quick question on valve spring shimming. i've read through some procedures (mostly on other forums, to be honest) and it seems that 130 lbs is the closed seat force most people are using with the comp cam 910 springs i'll be using.

does this sound right? that works out to essentially the same as the factory installed height. the plan is to check all the valve heights and shim only where necessary to bring it back to ~1.75"

also - i haven't seen anything about checking/replacing the valve stem seals. are they generally OK? i guess they would be if compression on the engine checked out OK - which it did.
