Eddy heads and what else !!

How did the holes strip? Was there an issue with the intake bolts starting or you just leaned too hard on them?

If you have them off, I'd suggest having them cut to reduce the chambers to 58ccs and get it to at least 10.5:1. Don't forget the intake sides so it fits correctly. Have the valve job fixed and if it hasnt been done. Have them test a few valve springs for pressures. Gasket match the intake port and shap the pushrod pinch, and gasket match the intake. That's what I'd do.
