There is a "P" stamped in the center intake port on each head. The pics don't do them any justice they are fully ported and can tell they were only ran for 1400 miles.
I'm sure they are alot better than stock, if no one ends up buying them i will just throw them on my 5.3 in my truck in Jan or Feb.

I think with 58cc and stock thickness gaskets, your at about 11.3... Go with a .060 you should be at 11.05-11.1 I think thats a good NA CR.
