Indy LAX or J-heads?

And also i doubt i have enough of everything else for a W2 headed engine to realy come alive,i believe that would take a bunch more camshaft,converter and gear,but i may be wrong there.
To take advantage of a W2 head is really the only way to run one IMO. It doesn’t have to be a maximum undertaking ether. Just a serious build.
Falling short of doing so, a regular stock head would do and not going the distance becomes a why did you bother question. Only reason not use a W2 is cost.

After re reading your first post, if anything, with ported W2 heads in place of the LA-X’s you could use more lift with 1.6-1.65 rockers since the W2 tends to breath very well at high lifts.

Well done (ported) LA-X heads do perform really well and a move to a W2 would probably not be cost effective or show any large gains with the build parts and cam.

*I Think* & IMO, your going to have a really nice engine when your done.

I am in the process of doing something similar with a few 340 blocks I have. They need to be sonic checked for there health and I want to swing in a 3.58 stroke crank for 373 or + cubes. I have a set of W2’s for this job that will be in the street.
I’m looking at slightly bigger solid rollers.
