There has been a few posts on Sb heads. I just went through them. Personal choices, rumors and all out race suggestions. I need a set of SB heads to move my 3300 lbs M body to consistent muffled 12.00's to run a 12.50 index this year. Short block - 360, .030, 520/540 w/ 290 duration, 10.5 compression with a 68cc combustion chamber and a 4.10 rear. Waiting on the final combo before I select a converter. All I need is to select a pair of heads. I have a set of 308's that need a total rebuild, but when you calculate the cost of a rebuild a new set, new iron /aluminum, is about the same. Any thoughts? THX

I agree.. the cost of rebuilding vs new your
better off with new.. I'm running W-2s which are
iron and weight more(about 40# per set) but they
can be made to flow well.. I have mine at about
312 cfm(might be 315 now)but they are about max now..
I have a set of W-5s but an having a issue with them
at the present time.. but I will get them right.. they
flow 319 at 600 lift.. both take off set rockers.. but
the alum W-5s are 40#lighter

Is there a ProMaxx Magnum equivalent?

Not that I know of but it would be worth a call. Man did they jump up in price.

Call Rod bloomer he has a very nice ported heads for someone looking to up grade over stock and use all stock rocker gear no high dollar rocker gear needed

Mid 12's, buy a set of reconditioned Indy heads for $500. They come with new Stainless 2.02 / 1.60 valves, bronze guides, springs, seals, locks, retainers. Take them apart, pocket port and gasket match them, and that should put you in the mid 12 range on the cheap.

On the Pro Max, what do you guys do for a heat crossover on a street/strip machine? I also looked at those Aero heads. Some rumblings about fit, finish and parts used by Indy.

Rod Bloomer's heads are the best value for the money. Great flowing, lost cost and much better quality then the others. Two versions are available, factory non offset rocker and off set rockers.

Agreed. Those are super nice pieces. And Rod supports the hobby

Rods heads indeed look like nice pieces, and I applaud him for all the time and effort it took for him to be able to bring these to market.

However....... That doesn't mean they are going to be the best choice for every build.
I think they are overkill for a stock stroke 360 in a 12 second car.

If I were making the decisions, it would get Edelbrock rpm heads.

Does any one have a web site for Rod Bloomer heads
thanks

Low 12s in a 3300 lb car? That sounds easy with a set of nearly stock magnum heads. As cast they flow 200, a little work if you have time and you're at 220-230. Or, a set of EQs that are 220-ish as cast. Or aluminum eddy heads at 240-250.

Cheap n easy.

On these... where do you buy reconditioned
Indy heads.. I wouldnt mind finding a set
of 360-1s at a reasonable price

Thinking may next two small block head purchases will be a set of W7 heads for a 48 degree block I bought since I got Jessel rockers and intake with it and a set of edelbrock Victor heads for my R3 block in my black duster to see if I can get it in the 8's

In your case stay simple and cheap to run the bracket you are aiming for

Edelbrock gets my vote as well. I went 11.50s with out of the box edelbrocks on a solid roller 11:1 360@3500lbs. I bought the heads, took them to the machine shop and had the valve job and guide tightness checked. Then I slapped on some springs to go with my cam and went racing. I later had Shady Dell to his stage II port job and install 2.05 intake valves. It went a best of 11.16@119.5. I just sold them to a member here, I almost didn't want to let them go they served me so well haha, the money is going to finish my Dana 60 and convert my tunnel ram to EFI though haha.

Shortly you will see a "Build me a motor" thread around them too.

Since most of these aluminum heads have no heat cross over, is there a tip to getting the intake warm enough on cold winter days?
