I am considering upgrading from B1 originals, and have heard good and bad about these heads. Scott Koffel has been a good guy to deal with and I would rather buy from him, but would like to know the scoop from guys that use them. I heard they have terrible valve train geometry. True or faulse? Also, will they fit a on wedge block? Do they need drain back lines, dedicated rockers, who makes them, clearancing of the pushrod holes, and mostly, what do they flow, I heard as much as 530CFM? Also, what does it cost to convert? Any advise would be appreciated. Special headers, or do B1's work?

Wedge Block ? NO they have a 12 oclock stud like a Hemi.
Drain Backs? Not Really
Original Headers? No not without some trick Adaptor Plates.
Valve Train ? You need to know what you are doing as you would with any HP Application.Jesel makes all the rocker gear in any ratio you want. the valve train is set up on stands like the BBC.
Pushrods require some work like tubes thru ports etc To get any size to run the required spring pressues.
I have heard 530 CFM but have not seen any. MIne flow under 520.
Scott and Dave can hook you up. It is there head after all. OR i can save you alot of headache!!!
Mike, what oiling system are you running?I'm in the market for one that will fit a stock early b body K frame? not sure if i'm going to a wet vac system or dry sump, any recommendations?

As you can see mine was buit with the dry sump. It was for a Top Dragster so there were no worries of a cross member. I suspect you could run the Billet Dry sump unit i have seen that is driven by the conventional distributor intermediate shaft  ?

I love b1 stuff but my next stop will be Predator...Unless there is a SMOKING deal to be had on a TS set up.

I heard they had trouble with those too. Something about knocking the mains out of them.

How does a cylinder head "knock" main bearings out???
Anyway there are a bunch of Predator headed engines that see 8000+ rpms and over 250 passes a year.
I shift mine at 9200 and the bearings looked new when it was freshened.
Call me if you have any questions about Predator heads.I will give you the straight story and not a sales pitch.
BTW,I have a set of wedge pattern heads the flow 545 at .900
if flow numbers are what your comparing.

It was something about the canted valve design and the piston shape with the wedge head deal, that caused excessive detonation. I really didn't want to have to change headers, as mine cost alot. But, it's good to know some have good luck with them. It will either be Predator or B1 PSO's when I make the move.

Lots of canted valve engines out there--almost every serious race head has canted valves.

the Predators would rquire different headers..you could use yours on the PSO if the tubes are big enough. The PSO is the best true wedge head currently produced, but..it cant match the flow of the the splayed valve heads like the Predator, TS, Big Chief, etc.

That's what I have to think about, whether the extra power of the PSO's will get me where I need to be, and I really need 150 more HP.
If your Originals are fully ported, I think it would be close. I think Pete Costa said he is getting a tad over 500 CFM now from his PSO. Thats about 75 CFM over your Originals and that would = 150 hp.

500 CFM would make up my mind. Then I'd just need money. If that's Pete at Best machine, I thought he said they would flow around 470 CFM, and I don't know if that's worth the $10,000 for heads, intake, pistons ect. That's my dilema.

I just got off the phone with Pete and he said his PSOs do flow 470 CFM. But in comparison to other Original motors he has built they make about 175 more HP! You might want to give him a call.
