Are these heads a waste of time, or would they be a good choice? Everything else on the engine is out for debate, but it has to be a 431. Thanks!

From the specs they look to be an excellent head for a race application with less than 500 cubes. Looks to me like they will work, but will want some rpm as torque peak may come in about 4800 rpm.

They out flowed 440-1's everywhere on our bench. Same guy ported both heads. -Kenny

We're getting ready to do a series of BB builds for CC starting with a steel crank 400 and stealth/victor heads then going to a stroker and comparing those heads with the MW Victor and then a highend build possibly with a Koleno Block. Std. port Victors IMO are an awesome head but require alot of pushrod clearancing. Only downfall. And they really respond to a good valve job/chamber cut. Brian Brian Hafliger

People refer to their suitability to small engines almost in the same vein as the RPM'S, which are more of a stock replacement. Is it because they have a broader spread of power and better low to midrange flow numbers.

I am willing to bet the reason they flow that well and can work with a smaller motor is the valve length, which allows a small port to flow so well. Same CSA, but a MUCH better port. 8.582, 160.18 mph best, 2905 lbs 549, indy 572-13, alky

Mick The Victor's have a good combination of port speed, valve size, and it's a raised runner head so it has much better cylinder fill. Brian Hafliger

I would like to build this engine with a street friendly cam ( probably a flat tappet because I have sticker shock from roller prices!) and I figure that these heads would be a better choice than the ez's because of the port size and my cubic inches. Am I nuts to think that i could make a strong running combo out of this?

I will be aiming for well over 550HP on pump gas with the 400 and a flat tappet cam. Brian Hafliger

For the money they are a great deal; Performance has been as expected and the only drawback is the work required to clear the push rods. I think I spent about 3 hours with a grinder to get them where I needed them. The benefit I do not hear much about, but was really good for me is Header fitment. I am running Hooker 2" headers in a B body and the fitment was better with these heads than stock steel heads. Only 1 place I had to modify and that was done with a small pipe, block of wood and 2lb hammer. Best performance with the heads noted in my sig... 6925039-NorwalkSept2011.JPG (97 downloads) 68 GTX, 9.38 at 144, Best Machine 540..

FWIW, I wish I was independently wealthy and able to afford testing my 452 w/ the old Stage VIs, followed up by basically OOB Victors, followed up by my fully-ported Victors. I'd love to see where the improvements (or losses) came from w/ each change, rather than going straight from the Stage VIs to the ported Victors.

You can be the test bed, so to speak. Mick 69 Dart GTS 440 mopar .590 cam, Edelbrock heads, 3200# best et 6.45, 106.78, 10.14, 132.88 mph, 1.47 60ft best 60ft 1.36
