Very disappointing #'s. A valve job and some cleanup should bring the #'s up some.

I guess 250 at .500 is wishful thinking with the standard SM head. Get your grinder out :D

I'm not worried about these numbers whatsoever LOL.. just interesting to look at and talk about.. I don't think I'm going to lose anything by putting these heads on except for weight...
