I would like to know if there is a quick way to identify older 48 degree W2 heads. I think I have a pair and I dont know if its worth the trouble to use them on my 410 stroker. Thanks
BTW: If you haven't built your 410 yet, I may be selling one of my new 48* R blocks (assuming that you haven't built the shortblock and the W2s are 48*).
48-degree heads are for 48-degree blocks, which you do not have.
A set of Edelbrock heads should flow at least as well as the earlier W2s when ported, plus they're aluminum AND do not require all the different valvetrain pieces.
