AFR Heads

What length valves are you checking it with?

According to the AFR website, the assembled SBM heads use the same valves as some of their SBC/SBF heads.

The taller valve would make the geometry issue worse, just like all the other china heads

 

[skrews]

After looking at my Speedmaster heads I went with 4.96 length valves. Depending on how deep I put the valve job 4.91 might be a better choice as it would help the geometry.

All I see is another SM/Edelbrock clone. Womp womp womp.

Something literally nobody was asking for. Oh well.

Hopefully at some point with more and competition some of these companies start trying to out do one another.

with what? a copied Trick Flow or W head.

I’d love to see an affordable aftermarket W2/5 head. C’mon Edelbrock!

Stock type, street head like TF but that makes a little more power or same power at a better price.

Only the Chinese could pull that off, they don't care what Ma Mopar says, Edelbrock does, they'd have legal issues.

Last I heard Speedmaster heads were up 145% and will cost more than Trick Flows unless something changes.

 

[skrews]

Am import version of the W2 in aluminum with good OOTB ports and modern chamber design. Team it up with a matching intake similar to the Victor or the M1.

Still the same price as they were 6 months ago from what I'm seeing on their site.

Yes, yes and yes! W2 style port & rocker design in a modern aluminium casting, with a good chamber. Take my cash.

The W2 is still a low port design.

If you are going to do all the work to produce a “modern” head it should be an updated W5.

I know what I’d do to update it for sure.

1. Raise the port another .150-.200.
2. Raise the floor to match it.
3. Add at least .300 or better yet .400 to the valve length so you can get the port that high.
4. Raise the valve cover rail .750 or better yet 1.00 inch.
5.move the exhaust valve at least .060 away from the intake valve and .100 would be better.
6. Move the intake valve the same amount.
7. No bigger than a 1.550 exhaust valve. The end user could install a 1.600 if they thought they wanted it.
8. 5/16 stem valves because they are going to be long and heavy.
9. Move the rockers over to match valve placement. This also removes a little bit of the angle around the intake port and you can get a bit more port width there.
10. I would change the chamber but it would look nothing like the Edelbrock/SM/TF chamber.
11. 50 degree seats out of the box.

When you type all that out it’s a W7. Although I don’t remember if they moved the valves that far. I do know they moved them.

Edit: and develop a tunnel ram based on the Holley Pro Dominator design.

I would love a nice readily available copy of a W head, sure that'd be awesome.

An aluminum W2, with modern chamber design and good "OOTB" ports would be the bees knees.

nobody would buy them, all super scared of the ''offset rocker''.

TRUTH TRUTH TRUTH TRUTH TRUTH TRUTH TRUTH THRUTH

Let's not forget the Chinese version W style head everyone is waiting for will probably have a Chinese 200 buck rocker system available. and also a 150 dollar intake too. Top that off with a colorful Chinese carb. lol
All for under 2 grand. lol

I'm fine with offset rockers.

Like I said, a nice W2 copy, in aluminum, with a modern chamber, good OOTB port, and room to grow.

If you're actually investing in a casting and tooling for a head, it doesn't seem like a big jump.

Maybe you could email that to Chung Chow Pang.

a nice W2 copy,

So you're OK with stealing so you can have an affordable W series cylinder head.
I believe the W series died with Mopar Performance.

I’m fine with that. DC/MP is functionally dead, especially for small blocks. Who are we falling on our sword for?

I think Brett Miller looked into it.

I have a full set of W5 engineer drawings I offered to him but he never got back to me. He probably has them.

I had to lie like a rug to get them. They showed some of what I wanted but not enough of it.

To be honest, the Bloomer head has been proven to make enough power to render the need kinda moot for a new offset rocker head. We already have the INDY head which is a better W2 head in aluminum already.
And anybody who is going to want something stouter than 700 horse potential of the Bloomer, and somewhat more with the rectangular port Indy is probably looking at the Victor head and or the W8/9 platform.
And in the LA world, with the continued more popular use of the Gen3 stuff, your teaching to a really small class.
I would say already, old school LA guys maybe 5 to 8% are guys looking to make much more than 600 horse N/A.
