That isn't really a very big cam. Very little difference to the OEM 340 type grind. I think that you had better do some checking to see what is wrong. Yes, it sounds suspicious to a head gasket but not nessessarly, they are not that notorious for going out if the surfaces are prepped and torqued correctly. Very few are retorqued.
Pull your valve covers and make sure that all the rockers & push rods are in place. Also check your coolant level in the radiator.


coolant level is full and emerald green.

The receipt from the machine shop from 2002 reads:
"Hot tank block, install cam bearings, freeze plugs"
"Balance complete assembly"
"Machine hone block for moly rings"
"resize rods
clean magnaflux, polish crank

"clean glass bead heads, do complete 3 angle valve job. Assemble."

The parts relative to this bill were:
8 Melling (sp) exhaust valves and 16 05940 valve seals.

I don't know if that gives anyone any real data on what the machine shop did.
