Subject: FTE Perf - die grinder ooops !!!

there is a commecial product called Belzona... their literature reads :

"Belzona Series Products are based on two-part polymer epoxy technology.
Belzona systems are used to solve an infinite array of industrial and
commercial maintenance problems. Belzona ceramic based coatings offer
superior performance over other conventional coatings"

We use it here at work for all kind of machinery repairs... crankcases,
housings and various machinery parts... super strong and I think

It is heat and chemical resistant (not sure to what temps). their web
site is, but I had trouble getting it to come up..... try
a Yahoo search on Belzona and there are several references.. It ain't
cheap...but hey, neither were the heads...

hope this helps

this hole from the outside, or should I take it to a welder and get it
solid filled, and the finish off the port with confidence?<<

If I had spent that much money on those heads and then spent that much time
on porting, I would fill that sucker in (very - very carefully, mind you),
and then refinish it. I would think just filling the hole with a bolt
would leave you in an undersireable port condition.

i read an article a while back about how john kasse ports the alum. C j heads
he designed. he actually cut a hole about an inch and a half high and over
1/2 inch wide in the alum. heads. directly in the side of the port into the
head bolt boss. alum is much more prone to the burn away compared to the cast
iron. and he said there was no worries with this type of porting on the
exhaust side..... and as for losing flow numbers on the bench with the hole..
that pump gas stroker made over 700 horse on the dyno..... i would just plug
it with a bolt... possibly even threaded rod.. with a nut welded to the top
to reach the bottom of the threads and protrude into the top of the port.
then just grind it away like a casting imperfection with a carbon
burr.......... taaaa daaaa.... its fixed and with no worries.........
