(Catching up...) OST-083: Salvage operation

[oldeskewltoy]

While I was able to do a great deal in salvaging this head - this was truly borderline where it should have been welded up and rebuilt. The fact that this was going on a mostly stock engine (California so stock cams), and the client not wanting to spend that kind of money helped me decide*.





cleaned and pressure tested... and tumbled. It is obvious that the challenge here will be cylinder 3




* - What also helped me decide was the fact that the decay was all inside the fire ring of the head gasket. The old head gasket - stuck to the head helped protect the head.




Porting proceeds.... Typical crappy short radius from a smallport head...




and exhaust work....





and a 4 panel showing just how much that chamber improved......





ready for re-assembly

Impressive how well that cleaned up!

That before pic looked so gruesome I was expecting a twist to happen somewhere in the middle. But it didn't and great job on reviving this head!
