$64???? I bought Napa head gasket for $18 and guess what, it said felpro on
it.
Hasn't leaked for about 1500 miles now.

Mark,
Mark, thanks again for your comments.
At this point, I'm really skeptical about re-using the copper gasket I first
tried, (even though there are less than 3hrs running time on it). The felpro
set
I ordered ($64) is supposed to be in today. I also thought I'd take this
'opportunity' to make some of the mods, that I had asked about in earlier
postings (adding PVC, and vac advance) to my intake manifold and dellorto
while
I had them off.
In any case, it doesn't look like there was any harm done, except for
getting
oil all over my nice clean engine compartment.
Thanks again.
- Bryan
