A quick and dirty tape measure comparison between a stovebolt head and the Atlas looks like it's doable. I'll need to make an adapter plate to bolt to the top of the stovebolt block with flat head Allen bolts, and drill and tap the plate for studs to secure the Atlas head. Longer connecting rods and a stroker crankshaft will put the piston tops and some pressed-in sleeves a little above the top of the stovebolt block, so the compression won't suffer much. There will also be almost 10 cubic inches more per cylinder (300 VS 250) and a MUCH smaller combustion chamber, so the compression should be more than adequate. I'll also be converting the cam drive to a dry belt and eliminating the chain cam drive and the variable exhaust cam timing.
12 port crossflow head- - - -24 valves, and dual overhead cams- - - -what's not to like?
