W-2 heads W/ hyd cam?

Chances are the W2's have been ported for high rpm. Not knowing the airspeed in the ports or the min. cross section, I'd have to say they are probably too big for that app.
But...you could try them since you have them. I would use the comp extreme hi-lift 285 cam but have it cut on a 108lca and install it 4° advanced.

Ditto, couldn't have said it better myself.
