Re: Valves.... ugh
Actually FiatFqctory I do. Crazy loud and was pretty sure it was 2 or 3 on the intake. I thought it might be AUX timing , but triple checked on build and retimed the cams 3x after.

SoCal - definitely running better with 3 exhausts set to spec and the one intake at least reduced some!!
FiatFactory - you could very well be right on the bent valve/head on a flat surface issue. I don't recall how it was transported etc, but I could easily see that happening. Can't recall what I did during the motor rebuild, but I'd guess 1 and 4 were on TDC and the cam wheels roughly at position - i know better than to freewheel the cams during build especially with popup 8mm domed pistons. I had the head off a year or two back to look for any piston kiss (none observed) and attempt to verify no AUX shaft issues - could have banged a valve during that take/off as well...
This'll be the third major motor repair this summer.
1) K5 Blazer with blown head gasket and cracked block...
2) 2nd K5 Blazer with blown head gasket and now hydrolocked on start
3) Fiat with head that needs to come off...
I think i know which the easiest is out of the bunch.
Still gotta order a couple of shims. Thinking about just buying a whole set off ebay
