Factory roller 360 and 308 head questions.

Yeah thats the number. I should have took a few pictures of them before I bolted them on.

I don't believe they are any different than the 308 expect for those air holes on the bottom of the ports.

It cam with 2.02 so I used them. Muscle Motors did the milling and bowl hog them. Eric over there thought the newer high swirl 308-576 were BETER than the J's and X heads, thats what he told me and I got them before talking to him.

I love E-bay....sometimes :-D
