John,
Greg (Craig?) Warren bought Don Byers "Full Throttle" (Laurie Byers is moving to Oklahoma).
He is located in Lake Elsinore, CA. 949-300-8457. Same shop as Don.
570 Central Ave. Suite F
Lake Elsinore, CA
He might be on spring break vacation. I haven't been able to contact him yet. My Pantera needs help too.

I need a recommendation for an engine builder/machine shop in Orange

Back story:
After sitting for 10+ years I finally fired up my engine a few weeks
ago. It sounded good for 10 minutes then I had a bad clatter in the
valve train. At first it appeared to be a loose rocker but there was
weird interaction with the valves of cylinder #4. I popped the head off
and found that the exhaust seat had come loose! While dancing around
the seat also made some deep marks on the piston head.
My gut tells me the piston is trashed and needs to be replaced. I have
a friend that says I should repair the head and go as is. I don't know
if anybody on this forum has an opinion.... But, when is a "witness
mark" a catastrophic failure in the waiting?
I posted photos on the picture forum at this link.
