Pro-filer Heads ?

do these heads use the same valve train as the c-head?

Not sure I've never needed heads that big, seen few sets, but I'm sure Randy or Charlie could answer the question.

any new updates ????

Hi guys. Hope you find this information useful. We have used the Thors on both a 598 & 638 engine with nitrous. We strictly race 1/8 mile. My experience is I think they performed better on our 638. That being said they worked good on our 598 engine also. The gentleman I sold my old Thors to has a top sportsman tube chassis Mustang & has been I believe 6.80's in the 1/4 at over 200mph with 2 foggers on a 598 engine. They are working pretty well for him. I just believe the more cubic inches you can put under the Thors the more they will like it. You guys take care & have a nice day!!!!

Tony Bischoff ran the Thors on a 646" engine with a lot of nitrous, in Pro 5.0. He went mid 6.50's@213+ at 2600# as I recall. They seem to like the nitrous, if you know how to tune it. He's run even faster in NMCA trim, I believe in the 6.30's.

Not sure but im thinking of going with the trick flow a-460 head with the 1.35 intake valve if anyone has a comment on those heads good or bad it would be great .

The trick flow a460's work great.

The Profiler heads WILL use a "C" cast style intake manifold easily. A 5/16" or so intake gasket spacer is needed; the bolt pattern does crossover.
I believe that Charlie Evans has those spacers IN STOCK.

Art Francis says his "Thor Heads" are a cross between the Ford "C" and "E" heads but, taller and use a completely different intake manifold and valve train.

Lou has the profilers!

I just did this deal with the c manifold on profiler , I used a 3/16 thick gasket i got from cometic , and the floors line up pretty good, match the roof line, and its all good. You'll need to slot the bolt holes a good bit, but they will work good. The only "issue" you will find is that the water outlets dont line up from the head to the manifold. Since i already had the heads bolted on and the rockers on it, i just filled in about 1/2" of the water outlet on the manifold , then ground the floor down some to make it all line up . I normally precheck everything, but i was guilty of not catching this during the mockups , if i had i would have welded up the water outlet on the head, then put a bung on the outside and brought the water out of the end of the head , I could then just glue the intake gaskets on and leave there for a good while during teardowns ( they are about $ 40 pr)
