You're right. That's a little bit worn. .033" over standard. Couldn't you just put a little bit of Bon Ami (if I spelled it right) in the oil and send it?

Well, got a little feisty, slapped a set of injectors in er and some oil so I could crank er up for some compression numbers.
#1 460psi
#2-8 380psi
Weird how 1 is a lot higher, but I did have to fight #3 a little, had zero compression. Ran some shop air down the gp hole, was coming out the intake.
Tore er down, bled the lifters for #3, then boom, 360psi easy.
Anyways I eagerly await your compliments of my work station

I've seen that before. Maybe it was just an earlier production block?

I'd throw it in and run it. I'll bet that the compression numbers will come up. If it's been sitting for a while, the rings may need to be reseated. I wouldn't be scared of those compression numbers. In fact, I'd be wondering how #1 ended up with that much higher of a number rather than concentrating on the "low" numbers. That is if I though about it at all. I just don't put a lot of faith in compression numbers. Especially if the engine hasn't run in a couple of year or longer.
I don't know how long the engine sat for, but I'm gonna at least pull the heads and put the studs in we got. Old man doesn't plan on turboing it, but we already have a set of felpro gaskets laying around, so might as well.
I'm trying to convince him to at least put comp spring in, but for a N/A application with an auto, think they'll ever be necessary? Should I just leave it stock springs?

Send it......run it on waste oil......move to AZ.......drive it till the wheels fall off, put em back on with 3" wood screws.....drive it some more......
Seriously, id roll with it.

They're not needed. They'll just wear out the rockers prematurely. Since I couldn't run the Typ4 cam I had, I now wish I had taken the Comp springs out of my heads and put stock ones back in.
Well, ain't no rest for the wicked.
Two pistons kissed valves at some point, and all have spider webbing in them. This one is the worst. #5
On another note, what valves do y'all suggest?

I'll just repeat what I said in the balancer post here/. I don't see the reason for different valves since aluminum melts way sooner than steel does. My opinion is that I'd just use N/A valves and be done with it. That may be the wrong thing to do, but it's what I'd do. I'd just stick to a bigger named company like Sealed Power or Melling.
I mostly want to change the ones that have evidence of impact with pistons, not necessarily swap them for turbo valves
