Update: We sent the heads out to get checked over and we have cracks in both heads at the precombustion chambers. Working with Costex now to see about replacements. Nothing here in Atlanta available through Yancey. Only the Penn. Cat dealer Cleveland Brothers, has to reman units available for near $7K/EA + shipping. Good times working with tired iron.
Costex appears to have bare heads in stock. Can the parts all be used off these old heads to build back these bare heads? Or should we swap out springs etc. for new?
Interesting note though, the guys that checked over the heads said that our valves were different sizes on each head. One head had 3/8" valves and the other 1/2" valves. The rep that called me wasn't there for the tear down and could not tell me if the valves were intake or exhaust. Will be trying to get the full write up to share later on when I can get it. I wonder if one of them was worked over in the past or taken off a difference machine?
