CALLING ENGINE GUYS/GALS

If the OP is afraid of it take the heads to a machine shop and have them touched up. Then pull the pan and pop a couple rod and main caps and check them out. If it makes him feel better plastigauge them while he has the caps off.

Yeah, yeah........I know plastigauge isn't the preferred method and I haven't used it in years, but I built a bunch of engines years ago and used it. All of them held together fine.

I get a kick out of guys turning up their noses at backyard rebuilds. One of the best running stock 383's I ever saw my cousin and I rebuilt on his Mom and Dads front porch. My Dad did the valve job, we cut the ring ridge out, dingleberry honed the cylinders and cleaned up the best we could. Heck we didn't even replace the cam bearings, factory cam or timing chain. It did get new main, rod bearings and gaskets. The ragged out 69 Road Runner it was in embarrassed a bunch of cars and was still running strong when he sold it a few years later.

Good luck to the OP. :thumbsup:
For the record, I did plenty of low-buck builds, had no choice. For others too, all ran great, not one had holes that looked like that. Like I said, Choice #1,.....lol! Good luck indeed, hope the rings break-in before they wear out!
