Reply to "Jack, what do you think? 32 valve 351C heads"

Peter Aaardema's 4-valve heads have been around since the '80s. They were originally pushrod-activated with linked rockers operating dual intakes & exhausts- not what one would call a high-tech arrangement. Such a setup is immensly easier to build on straight-valve heads such as Chev small blocks & Ford Windsors. Clevelands and big-block Chevys are the only stagger-valve engines, so these heads must be fairly new or are Windsor conversions. I've never seen any dyno trests published for any engine running these heads. I'd be especially interested in the rev-range of the setup, since 4-valve heads typically make most power at higher rpms, and pushrods in the design seem to limit this. Dunno.....
