Little tight on the valve seal clearance but going to give it a shot anyway. Springs tested at 110lbs at 1.870" and 285lbs at 1.3". They are likely Comp. Cams 972 SBF or equivalent 1.460" diameter single with damper that I had from trading years ago. They fit my hardened SVO retainers perfectly. Now I have to hunt down about 7 correct valve seals as the spares I had were to thick and hit the retainers at max lift, which is .550" on my cam.

Can ya get the guides cut down?

I am sure I could but I am only upping my lift .020" from the old cam. Do you really think I will have a problem, I already have way to much money sunk into these heads?

On bare castings, knocking down the guides should require your machine shop just 4 minutes of their time and the guides will machined to an OD for positive stop seals in the same process (assuming the proper cutter).

110/285 lbs? Toss a 0.030" shim under each valve spring while you're in there.

You are about 2 hours slow Paul, I just got back from the machine shop and could have picked up a pack of shims. I will have to look through my Cleveland stuff, I think I saw some in there.
