I would be very interested to see/verify if the Ace Magnum cams will work in the AVL with our new Ace cylinder head mods. I anticipate that it would, since we use the same springs, cams and valve hardware in the Fireball without any drama. The main difference with the AVL would be those very long-stemmed valves. I think it should work.
With Magnum Cams and our roller rockers installed in the AVL, it should reach .500" lift.
In any of these cases of higher lift, piston changes would be required to clear the higher valve lift over TDC.
If the stock valve lift is retained, then our Ace head mods for the AVL will at provide more flow all thru the entire existing lift range, and about 25 cfm more peak flow at the same max valve lift. That is pretty substantial.
With S Cams that have the same lift, but longer duration, it could definitely add up to some power, without having to get involved with piston changes.
With piston change allowing higher valve lift, then it would really wake up even more.
