Though aluminum is the rage these days, I dunno....W2 heads look to be just as viable as they ever were. Haven't been able to get any flow data yet, but these look nicer than the previous ones I have worked with. Can't find anything ugly that I don't like in the castings, machine work looks clean and so on. Looking for differences new vs. old....if anything the castings have more of a "squared off" appearance on the outer walls of the intake ports (looks like more material?). The deck surface also appears slightly thicker to me than the last ones I had, but that's just from memory. One thing that stand out...this is one of those oddball parts that the casting number matches the part number, which almost never happens. These are the 769s. Anyway I got a chance to check them out and maybe you'd like to see them too. I'm sorry my camera skills kinda suck for getting shots of the bowls...I tried, but the pics of those areas didn't turn out well. 7115830-w2heads1.jpg (1912 downloads) Last edited by ZIPPY; 03/13/12 12:17 AM.

Sorry for the lack of gory details, maybe somebody has flow tested them and can post up...I have not taken the time to ask or look, to be honest. I mostly intended this as a "hey do you remember them?" kind of deal, and thought I would mention there are some new ones out now. 7115869-w2heads5.jpg (575 downloads) Rich H. Esse Quam Videri

The reason I ask,is the last shot appears to be a granite inspection plate that the W-2's are sitting on. Am I correct? Thanks! Randy B. BTW...I sent you a PM about your Mopar presents! THANKS!!

It's hard to say with any authority because I don't have the old ones around to compare them to anymore...and I'm sure not enough of an expert with them to "remember" the shape. Heck I can hardly remember what I had for lunch yesterday... Rich H. Esse Quam Videri

The 18 degree heads were good, used standard W2 rockers and worked with either a 59 or 48 degree block, flowed about 250 CFM @ .700", the 15 degree heads were better---could flow up to 290 @ .700" if "prepped" properly---but required a 48 degree block and special "oil through pushrod" rockers(Jessel). There were a few sets of 12 degree heads---primarily through Stanton that were real good but required T&D rockers.

But heavier, use a special intake/rockers, and cost more (quick look put these in the $1100 bare range). Not too hard to understand why not too many people run them anymore based on that. I think more circle track guys run them because some rules force "iron heads" on the teams.

The Eddys are a nice, affordable street/mild performance head, but I would run a W-2 over the Eddy in a race effort where cost is not a factor. I've seen W-2s go 320+ with good air speed and a 15* closed chamber W-2 on a 48* block is no contest, especially if the right guy does the port, chamber and intake work. Plus, with a little grinding, you can tell the brand Xers they just got drilled by an all iron 340.

I dont recall the top of the runner being flush with the VC rail Mike I was thinking about that last night and could not really remember, so that's good input. It seems like they have alot more meat on the sides too, The outside of the intake runners sort of looks like a box or a rectangle, with corners slightly rounded off....more boxy looking than the older ones for sure Rich H.

There have been many improvements over the years, combustion chamber being the best change IMHO. Prices seem high until you start comparing bare for bare with aftermarket cast iron race heads for the smallblock chevy crowd, then they don't look so bad. Cast iron heads aren't so much cheaper any more. R.
