"Had the intake off of my port
"Had the intake off of my port engine, model 350-454. Looked inside and noted a significant amount of build up on the back of the intake valves. Suspect combustion chamber and top of the pistons will look the same.
I have long suspected loss of power and increased fuel comsumption on the starbord engine was due to this but forgot to look for it when I had that intake off.
I have tried in the past to run SeaFoam down the carburator and also tried ATF. Appears it did not do much good.
Aside from pulling the heads is there any solution?"
