it doesn't have heads on right now. the ones he gave me are brand new don't know what brand tho. As for Serviceability what do you mean by that?? What parts should i replace
By serviceable, I mean: pressure check good, good sealing valves, correctly chosen and set up springs for your cam, square surfaces, good threads, etc...
You might not have to replace anything-I was just curious where you are with the heads.
I guess I read over the part where it didn't have heads. So, he gave you a set of heads? Are they aftermarket or refurbed stock? Do you see any casting numbers? Can you post up a pic? I'm sure someone on here could ID whatever you post.
