which heads for a 408ci?

if you are able to port the heads yourself go the the econo w-2's. there was an article in the nov. 2001 edition of mopar muscle that blew me away on how good these heads will actually flow. they will outperform the eddy's hands down. this article shows how the w-2 outperforms practcally every aftermarket aluminum chevy head whether as cast,cnc ported, or running much bigger valves. these heads even outperformed a fully ported 460 ford aluminum head with 2.25 intake valves ! i have the flow chart for these heads and the article that they did on them i just don't know how to paste it to this page. anyways mopar muscle did an another article building a 408 stroker and when using these heads the made 607 hp at 6600 rpm with the smallest roller in comps catalog and a tunnel ram setup. they also made 583 hp with a m1 single plane and an 850 dp holley. these numbers are very impressive. the article was called 360 a-bomb and the articles started in the january 2002 issue. i can try emailing you the w2 article if you would like.
