Anyone do a straight across swap,from ported factory heads,to worked W-2's?

W2's are totally worth it especially if you are limited to an iron head like in circle track or something. I went from totally worked EQ heads that flowed 300 cfm to W2's flowing 300 cfm on a 416---Went from 560 hp---590 hp. May not seem that impressive but it was. One of the best inline valve head designs ever. J.Rob
