Exactly, It’s not all about the flow #’s. My W2’s prove that.

I’d love someone to cast a somewhat affordable, aluminium, closed chamber, oval port W2-style head with a CNC option. I know Indy’s got the high end options.

It would open up the W2 world to a lot more Mopar fans, there’s just not that many W2’s around. Especially down here. Then watch the Ford Cleveland getting very nervous..

Hahaha! You even made me search the website immediately :D . Would be good if Eddy, TF or even 440source came up with something.

You think someone would, If they could do a similar price point as a TF top end, probably would sale pretty well.

Yeah, you would think if they can cast all of these old dinosaur heads, they could do a W2. It wouldn’t be any harder to do.
Then again, it may be a case of putting your big boy pants on and just stepping up to the Indy’s.

Indy 360-2 is the aluminum version. i don't know much about the indy stuff. never looked into there heads all that much. i've had W2's for so many years and they performed so well, i couldn't take them off.

Have you ever run a W2 that was CNC ported? Or has it all been hand ported?
There’s a circuit racer here in AUS who runs W2’s on a 358ci (340 block). It’s making 660+hp.

No, my W2’s were hand ported by Jesse Robinson known as RAMM on this site.
 
People get all hung up on the term, "cnc ported" but that's just a digitized copy of someone's hand porting job. It the make duplicates faster/easier, to increase profitability

I googled and this ad came up. Are they no longer available?

Looking at the flow at 600 lift this seems very common on the standard architecture type head as the limit. I know with my Eddies that flow 288 cfm on a 10 inch bench with a 2.02 valve the floor is very flat.

Your looking at a add for heads no longer available, and were way down on power. Those are not the bloomer heads being discussed here

Ask them. But essentially, they are a speedmaster casting that has there own port design. And seem to make great power

If that's the case it comes down to who ports them and what hardware they use since everyone has access to the casting.

Brett Miller did the previous ports so it wouldn't surprise me if he has done the newer ones as well. More power is relative, either you make more by increasing it and using more air and fuel at the same conversion cfm to hp or you utilize more of what you already have more hp for the same cfm.

Brett did the original port and they were a dud. Worked so poorly they shelved the whole project.
These new ones were done by Vic Bloomer by himself. Starting from scratch
If I had a set of heads and could have anybody port them, that is who I would use.
It’s why I wanted a set even before anybody had been down the track with them

Can you define why they worked so poorly?

Yeah I get all that. I thought he may have a program for the W2’s

Because CNC doesn’t mean good.

I’ll take a set of hand ported head by a pro than some off the shelf bullshit CNC porting.

Agree 100%. Here's what my Eddy's flow after HAND porting by a pro. Check out the mid lift numbers especially. These kill out of the box TF's.

.100 64
.200 155
.300 233
.400 280
.500 298
.600 307
.700 309
.800 311
