Just talked to Radar at R&J Perfomance in Hudson,Iowa about opening my MP aluminum 383-440 heads up to max wedge...He also said to use an Indy intake for the 512...Opinions??Is it worth the money??? Thanks!! Ted

You might want to do a little more research first.I'm no head porter,but I thought that you did not gain much with Max Wedge sized port openings,unless you relocate the pushrod holes and go to offset rockers? Seems like a larger port opening,with the same cross section at the pushrod pinch would do more harm than good? Hopefully some good head porters on here will jump in and let us know.  Keith

Radar knows what he is doing. It certainly comes down to bang for the buck, but the 512 will like the addition. It opens up a better intake manifold as well. Again, Radar knows what to do .

going to a maxwegde port is about 30 more hp
not all is in the port size but the intake manifold too
you need to feed the 512

All I can say is Radar ported my heads and picked my cam, the results say I went with the advice of the right guy!
From what I read and hear, motors in your cubic inch range need port volume. The max wedge port is the right size for motors looking to generate peak torque around 5,000 rpm with roughly 500 cubes.

This is correct. I have done many of the 500-512 combos, and they all respond well to the added volume, and I think the intake plays a big part of this. Seen it in the Indy SR heads as well. Have those same combos with and without MW and they MW flat out wipes the non MW combos.This is also why guys seem to bitc* about Indy 572 heads that barely flow better, or " not as good" as their 440-1's. They dont understand what the volume is doing in that application. You just cant get completley stuck on flow numbers.Same with this MW deal. It works because of the added volume and how that supports the cubic inches.
Had a 440 bracket car that had run 906's, 915's, prepped Ebrocks, and MW Ebrocks, and MW is hands down faster, and even wothout the correct intake manifold.

I'm not knocking Radar at all,as I don't know him.I just thought I had seen results from a couple of different porters going from a stock port window,ported,to Max Wedge size.The gains were minimal for the work involved,IIRC.

If memory serves me correct he had a lot to do with the design of the B-1 head.

yes i would open the heads up but i would run the 337 intake with those heads and never have to worry about sealing the valley up. ever
