Hello All,
I am about to start the rebuild of a 5mb gas engine and needed to know if the head bolts are the same as the 3mb engine, if so anyone have part numbers??? Thank you all in advance!!!

I believe that some of the Head bolts were shortened a little when they changed from a 7:1 to 8:1 Head ... but I'm not sure about the 3mb to the 5mb, My guess is that they stayed the same but we will see what others say ...
Do you know what year your 5mb engine is from?
