I'm at a crossroads with my upgrade path for my 408 stroker. I can take my Edelbrock Performer RPM heads and have them ported, new valve springs, rockers, and a new set of headers (currently have some junk Hedman 1 5/8).
Or I can get a set of W2 Diamond Aluminum heads rectangular port that have been ported and come complete with valves, rocker stands, iron adjustable rocker arms, and springs. Valve job was just done on the heads and it comes with a ported intake and a set of W2 headers for 25xx.
I realize I'll spend 15xx-2k having my Eddy heads ported, plus 1.6 rockers (I have 1.5 Comp rollers now), new valves, and a set of bigger headers (likely TTI). Plus I'd have to buy a different intake if I want to get away from my perfomer Air Gap.
So all that being said, would you go to W2 heads if given the choice? If you would go with W2 aluminum heads would you go with used W2 aluminum heads or go for new ones (assuming you can buy them new that is)? Is 2500 a decent price for all that stuff assuming they are in good shape? Does anything need to be done to my block to switch over to W2's?
From what I've read these are (or at least the iron version) a really good head for big power? I may ask the guy if I could have the heads checked out at a reputable local shop to pressure test them and flow bench them to see if they are screwed up or not.
