I happen to own a SOHC so playing with the cam timing is always gonna be a compromise between inlet and exhaust (could not change the exhaust to inlet angle).
You mentionned your SOHC truck, I assume it is a parallel valve engine and a 2 valve and if it is not a flat head, then there is no chance the valves could ever hit the piston except maybe at full lift.
(being an austin mini enthusiast, I know than you can fit the big bore engine head to the small bore engine whereas the exhaust valve overhangs the block !)
