The head bolts and water passages are close, the problems to use the OHC head on a Chev block is I'll have build some way of driving the belt, a belt tensioning system, , a fuel pump drive, oil pump drive, distributor drive, oil holes in the right place to supply the head and cam, drainback holes to get the oil back to the pan. Maybe leaving a stock cam in the block will solve the oil pump, fuel pump and distributor drive problems. The tensioner and drive may be adaptable from the Sprint engine.
Yep, it would definately present some challenges. Also a longer cam drive belt too. Can't be any harder than welding 2 SBC heads together and fabbing all the items together to make that hybrid head mod work.
