I have been doing some research on these heads and one BIG plus is the 11* design. Lets you install big cams without flycutting, how big, I have yet to find out. ET Ps heads also flow like crazy. I'm basically sold on em. Check out ET Performance for more info.

Seriously though those heads look great(and have threaded spark plug holes as far as I can tell). Make sure you let us know how they work out for you.

Nice heads
However, I would clean up those tool marks near the spark plug hole shown in the close up of the chamber.
For what they cost, you'd think that it would be cleaned up..or am I nit picking?

Ok, yeah, your nitpicking.lol
actually your not, I think some of what you are seeing is reflections from the flash. My pictures alwats come out like that too, that is why I never post them.
