I gotta agree with the B1 stuff. The 440-1;s would be a distant second. I went with the 440-1's maxed out on power, had about as much money in to them as B1's would have been. And probably 50-100HP less.

Its been proven that the B1 stuff runs pretty good with just some prep work, no need to go all out. Yes its more money, but how much money will you spend later, changing the whole combo?

Don't you have to buy special pistons to run b-1's ?

If you don't have headers, or rockers yet, then I would go with the 440-1's or the Victors. That way you have room to grow with them in the future. Either head is capable of making quite a bit more power than a stock block can handle.

If you already have headers for a stock port location and standard roller rockers, then a set of EZ heads CNC'd by Jeff at Modern would be the hot ticket like AndyF said.

I have a set of EZ heads and a set of SR heads that have been CNC'd by Jeff, and both flow right at 350 cfm on the intakes, but the SR's outflow the EZ's on the exhaust by about 20-30 cfm.

i already have the headers and rockers and i was trying to figure if it would be worth going to the b1 heads. i know the sr's flow 355 but i had heard somewhere the victors would be quite a bit more. i would love to have the b1's but not sure i would want to spend that much.

I agree Fish!
Why would you spend all that money in B1 stuff
and put it on a stock block.

I really think Stealth's CNC'd by MCH could put
a stock block to the test.

They say over 700+.

Keep buying those China Stealth heads and you maybe looking for a job to go along with those heads.

I've made 700 HP with a 518 C.I. 910.25 to 1 comp. ratio low deck with MCH CNC Eddy RPM on pump gas, I will(hopefully) be dyno testing a 527 C.I. 12.4 to 1 comp ratio 440 bock with SR heads with max wedge ports soon. Hopefully in the next three weeks if everything at the dyno shop goes okay I will post the results, my Eddy heads flowed 310 CFM at 28 inches at .600 lift, my SR flowed 340 CFM at .600 lift at 28 inches on the same bench on two different days months apart. The 527 has more cam also and it will be tested on race gas I hope it doesn't break on the dyno and make a mess and embarrass me
