The problem is most guys never wanted to buy the valve train and cried about what it costs. Those guys think they can make power with a stock rocker. Will never happen.
Guess it depends on the goals. My stock rocker, stock port location street engine has outran quite a few W-2 street engines. If I had Eddies, I would give Rod's heads a try, but I really don't want to give up 15 cc of port volume compared to my AIRWOLF 220s, and no, I'm not interested in an offset rocker.

Most guys can do the same thing my engine did with Eddies and a stout roller cam, mine is a comp flat tappet that is very nice on the street, 269/275 @.050, and 600/601 lift on a 111 lobe separation.
I could ship Iron Mike my AIRWOLF 220's, and I have a feeling he'd come back with disappointing flow numbers and dyno numbers...just think after two sets of heads, maybe the problem lies elsewhere.
