DON’T BE FOOLED!
I think the main issue is supply. These guys are doing this as a after work type deal, it's not a production type deal. And I would SERIOUSLY doubt they are on the same level as a W2
All the work is behind them now. Years worth.
The bare castings are being run in groups at BES through the CNC program. The valve jobs as well.
The only thing they have to touch is the spring setup for each customer.
As far as production, if anything, they are capable of cranking out more heads than probably the market will demand. I know they currently have 8 sets in inventory. So supply isn’t an issue at all. They can make more.
Regards W2 stuff. I think these are better. And maybe only marginally less upside than a W5 head.
Interestingly, for one season( before I broke the cast stroker crank) I ran my W5 heads on a flattop short block with a flat tappet cam very similar to what I currently have. Both 260@50, W5 cam had a bit more lift.
Both ran/ run almost identically. Cars weighed within 20 pounds of each other.
Fast forward, I ultimately went to a full bore X block 273@50 700 lift roller, dominator, 13.5 compression, etc, etc, etc deal. Light rings, pretty trick deal.
That motor ultimately went 9.50’s at 140.Not bragging, but not many W5 deals have run much if any better.
If you look at what Vic Terry has already done with his Bloomer heads, ( quite a bit faster and quicker with way less compression) but admittedly lighter, they arent very far behind the W5 stuff at all. And his camshaft is a good bit smaller.
I have yet to see W2 bracket stuff that can hang. So, based or personal experience, I think this new head slots somewhere in between those two heads. And the casting quality/reliability/ cracking worries is miles better.than either, obviously.
Not to mention header availability, intakes, etc. all easily available with many choices.
