Has it been running fine? Could be a valve spring etc..
If you just installed it yes I would be checking for a lean condition.

It could be a number of things if the engine and tune-up ran fine for three years it sounds like your head gasket was the problem. We just did a pro charged 502. Same problem blown head gasket was it. We built a nice package with his 502, pistons, custom cam,AFRs and a few other goodies made close to 800 hp on the Dyno.

Well the problem has been found.
THe original head gaskets let lose. More proof that the stock gaskets are not set up for supercharge applications. They were squirting into the intake and thin between all cylinders.
Its amazing the thing ran let alone ran as good as it did. No other damage what so ever.
