I’m not worried about replacing the bolts. I was more concerned that the bolts aren’t press fit. The only reason I would reuse the rods is because the engine is supposedly blueprinted and balanced. It shows signs of it... some of the pistons have been drilled.
Plastigage the clearances. The other reason to pull it apart is all the crud in the water jackets.
Like I said, the engine was rebuilt previously. It has forged pistons and a new oil pump and pickup. The rods are stock. It has a “purple” cam but I don’t know which one. Not even sure if it’s hydro or solid. I’m guessing hydro cause the valve train doesn’t look adjustable. Solid push rods? That seems weird. Mains look perfect. Everything looks new.
