Looks like a nice head.. I dont like the exhaust
bolt pattern.. its biased to the low side and
leaves the upper portion with less clamping load
EDIT
What rocker gear do they use and what intake

Flow bench says?

So there is an Easter bunny!

Chamber photos?

Flow bench says it's a very good design, very interesting how Rick built this port....
The pinch is kinda small because they left the opening just slightly lager than std. LA. So the pinch is 2.5" then it opens up and gets really large at the Short turn...but on a 4.030 bore it goes almost 380 cfm at 1" and what really impressed me is it went 282cfm at .400 lift on a 4.030 bore!
Cool thing is, there is enough room at the pinch to open it up to 3"!
SCE is working with us on the intake gaskets, TTI will have us a header soon...CP is doing the pistons for us, and TD is working on both a single shaft setup to go right on the head OOTB, and also a Bar/individual setup with milled pedestals.

I'm putting them on my 396sb as soon as I have the pieces to finish it.

looks like they could have raised the intake port a lot more

380 through that little pinch? Awesome! I think BPE is gonna start selling a bunch of 4.25 stroker kits.

Did it flow more on the 4.155 bore in the picture?

The head been welded on? Looks like fusion lines around the intake ports.

I noticed that too and was also wondering how you locate your heads on the bore. I drill and tap my head adaptors so the head is located off the head bolt pattern. I tried clamping like you show in the picture and repeatability was an issue. Can't wait to do some testing myself soon.

What's with the big voids on the intake face?

Just to make you have to think a little harder about sealing it all up.

Can I asked what the did at .600"? The numbers I saw showed them peaking about .800. Curious what they did at the "street cam" numbers.

This sucks. Had my heads in January, been at Crower for rockers. They told me another 2 months, did I want them sent back? The stands are milled, so until someone makes a bolt on pedestal rocker, they are just paper weights. Waiting again....

Are they 59 degree only or will the pushrods clear on a 48 degree block? Said the guy with a 48 degree block wondering about what heads to use.

I have a set of jesel 48 degree W2 rockers.

Interested in the .600-.800 numbers too....thanks!

So the 2.15 valve definately clears a 4.03 bore? !!!!!

I had to hurry and get the heads out so we can get all the parts coming to do an article...I didn't get pics of the chamber but I think it' pretty damn good!
Yes they move the intake valve over a ton!

Intake flow#'s on 4.030 bore:

.100 70
.200 145
.300 221
.400 282
.500 310
.600 330
.700 345
.800 356
.900 363
1.00 367

No welding, they are cnc ported and the ports measure out very good IMO. On the bigger bore, they topped out at 385cfm at 1.00".
So far I'm liking them, but they are HEAVY!! All the whiners who hate cast iron heads for their weight are gonna feel pain in the lower region but all well ;-)

Thanks Brian .

Right on bro !!! 👍🏽👍🏽👍🏽👍🏽👍🏽👍🏽

I'll bet the fitting the 4.03 bore had to be a major design parameter being they went with a 2.15" valve.

Do they have a milled pedestal version?

I agree getting 280 @ only .400 is kind of "holy grail" territory for a killer street wedge head. anything over 325 @ .600 is another great sweet spot.

It's kind of unusual to market a high flow at High lift head with extra head bolt provisions...but with pedestals and a 59 degree valve angle...hope a 48 will work...or they can be machined to fit without a ton of work.

Looks like where the clay radius cleaned it off--LOL. J.Rob

Might be best to mill it all flat and drill and tap 8 rocker stud holes and use an existing rocker for a che... er I mean magnum.
