pitted head

[cwhubb]

Hello everyone, can a head with a slight shallow pitting in the combustion chamber be repaired and if yes, how do you do it?

A picture would really help here.

If it's truely light and shallow it should not be a worry. The volumetric change is inconsequential.

a little prequel...I havent seen it in person yet, its a set of 915's one is good the one in question is pitted, The question is, assuming its shallow pitting and not at the edge of the chamber how would you repair it.

it wont cause uneven combustion temperatures and cause more damage?

If the pitting is along the chamber walls or roof, and it’s severe enough to cause a problem....... for something as common as a BB 915 head........ you’d just find another head that’s in better condition.

If the pitting is on the valve seats, you can have new seats installed, which is generally a good idea for the exhausts anyway.

Pitting in the chamber would have to be pretty bad to for the head to not be usable.

he wants 200 bucks for the set of bare heads

Hard to tell without seeing them if they’re worth that or not.

If they’re usable cores, that’s a fair price.

I'm hoping, Its a 3 hr drive from my place but, its worth it because he has a lot of other parts I can use thats worth the price

I had someone send me some 516’s to rebuild not that long ago.

They didn’t “look” that bad, but the water jackets were filled solid with rust.

They found some better cores.

The lesson there is........ look them over carefully.
