AFR, if you go with aluminum. Are you looking for aluminum heads.

mark, at mer used the profilers on too olds motors...go back and take a look at the dyno numbers, they speak for themselves like 1240hp at 5800rpm 6.5lbs boost

Canfield 350's...out of the box.

Everyone here has a favorite for their own reasons, but the guy building your motors should have his own combination and after all isn't that why you picked that builder?

Just my opinion.

I also like 18 degree dart for this CI motor. Big Chief, Big Duke and Profilers are also good choices. 705 is a BIG motor!!!

Re: Cylinder Head Choice For Blower Motors?
 

To get 8:1 compression on a 705 you need a total combustion space volume of over 200 cc. Since big chief style heads were designed for 15:1 drag racing engines, they have very small combustion chambers (65-80cc). What piston would you run?

now thats hittin the nail on the head!

What if your going to build your own?? I am looking at 650" or maybe 665" NA... I like the idea of the Dart 383cnc's.. but I am guessing..
