I am in the middle of building my first B1 combo. I will be able to give a good compassion to the -1 heads. I currently run a 528 ci ,mega block,and nothing off the shelf rotating parts.I am using the same cam, crank ,compression ration..etc .I'm changing the heads ,intake and headers. When I'm done in the next 12-16 weeks I will give some info up
I really think you're going to need a B1 specific cam, or you won't see the real potentail of the heads.

B1 originals . I have compared them to the pso . It would take allot of work to fit the cast intake to those. I have had the heads cnc'd and did a lay over onto the pso and there sure is allot of material available on the pso . ....one day  .
Kool,will be a great comparison!!!!
My lowdeck -1 540 makes 900ish...
The RB B1 original 588 made 1050ish with a little more comp.& cam and surprisingly on 500rpm difference in peak power..
Amen on the PSO'S...I've never ran the top/best heads and PSO'S will be my next head!!!

Josh do tell who is making the CAST aluminum block? Asssuming this is a 5.0 or better BS block? Be nice if they made a 4.9 bore space piece so one could use up the avaiable pro stock heads out there that are plentuful.

i think a 604 w/B1s would make a good street engine..i would use a purple shaft cam and have the best of both worlds...  
Step up to the 650 Comp flat tappet and I bet you would have a winner  
My uneducated , untried recipe; 604 with B1 heads, Comp 650 cam, Titanium intake valves in 2.3 diameter, 1.6 rockers, tunnelram with twin 750 carbs. 2 1/8 headers 35 inch long, 4 inch collecters. Use a small combustion chamber with a big dish piston for 11/1 compression?
Yes! Greg!  and this would go in a 63 Dodge Polara...vintage S/S clone

Big inch nitrous engines days are numbered in heads up racing , a turbo small block will eat most 844cid nitrous cars at the same weight . (And be easier to maintain and cost less . ) Just look at the 2012 SCSN pro street race .

I liked the b-1 heads but they just didn't make enough power to go TS racing naturally aspirated. Anyone have any used Predator heads for sale..

How fast do you need to be in T/S? And at what weight?
