W2 heads I think they are ready

I’ve had these around for a few years and am getting around to using them.
I bought them on fleabay with a victor jr intake, which I’m not a huge fan of, and found a Strip Dominator instead. I installed new guides, and new valves actually everything’s been replaced.
I polished the chambers some, roughed in the port work, and let a buddy wrap up a valve job, and some touch up work.

Didn’t bother flowing them, as I’ve put these on a flow bench before and there usually decent.
W2 heads have fairly large ports to begin with, and don’t require much work on the port intake opening, most gains are under the valve, and in the bowl area, and if you mess with the opening airspeed can decline.
Years ago I was working at a shop that took a set to the next level through raising the port floor significantly, and thereby kept the airspeed up, and airflow wasn’t tumbling or stalling, and the ports did not get all that much bigger, they just raised them, though I never got to see them on a car.
Loren Zeedyk was hanging around the shop some at the time, and probably was an influence. He had a lot to do with the development of the W5 head I understand and I have a set. I was also lucky enough to see his work in action on a car the shop campaigned that set some track records around me, with Zeeker heads, and intake, and I believe Don Dye did the carbs. I’m wandering and reminiscing. He was a great guy Loren.
I intend to put these on a street car, that sees occasional track time, and if we get through this Covid19 will be at the track again.

What’s your results with the old W2 heads?

A few years ago we did a dyno manifold test on my W2 head 363 motor it had a gasket matched Strip Dominator we swapped on an out of the box Victor W2 and it was a 13 H.P. increase, my heads weren`t heavily ported. I still have the 363 ( 360 magnum short block W2 heads) it is being redone for lower compression ( 11.5 to 1 to 9 1/2 to 1 ) for pump gas. When I was building my current 408 ( R3 block ) I purchased a pair of W2 heads for the build but sold them to get engine builder recommended 360-1s , the 408 makes good H.P. and T.Q. for low compression more than I expected but I wish I would have kept the those W2s though. The pair of W2's I do have came off a complete 12 1/2 to 1 340 I bought over twenty years ago for $2400 a steal by todays standards ! My 363 actually made 22 more h.p. with less cam and compression then the 12 1/2 to 1 340 : 10.40s vs 10.80s in my 3150 lb. Dart. My current 408 has ran 10.69 a best but is ran on a throttle stop to run 11.50s for Sportsman Eliminator and 11.50 Index racing.
