302 heads to 273 - head bolt help

elm13 said

Forgive my ignorance. I hired a guy to rebuild my engine. He decided not to finish so I took it back and am trying to finish myself. I have 302 heads going on the 66 273. He told me I need specialty made head bolts for this application. Where do I get head bolts for 302 heads into a 1966 273?
Thanks for any and all help!

Before you slide the engine back into the car........if you are still using the original 273 exhaust manifolds, check fitment and make sure drivers side lays flat to the head. Due to the reshaping of the head casting when the air ports were added (those can be threaded with a 1/4-20-unc tap and plugged with 1/4-20 set screws), carefully grind off the pad till manifold sits flat.
