I have an unfired 416/340 engine with MM parts in it-crank, rods, pistons. Even though it was built by one of the best I now have concerns about it because the response to this particular problem from MM Mike is well...poor...and leads me to question whether work I was charged [balancing] for was actually performed.

I would like to inform the epoxied hemi head engine builder who is lurking here that he needs to read and understand the excellent post by Bob George .

I have had a bunch of pm's about the epoxied head

Tick tock Dave. Here is your last chance before I let the cat out of the bag.
