You would be a lot better off with using a newer better designed aluminum heads like the Eddy Victors, Indy 360,360-1 and possibly some others that I can't think of now scope
The W2 where developed a long time ago in the early to mid 1970s work
The P5 and P7 heads are way better than the W2 work
Better airflow means more power up boogie
