it does bolt on, the blocks are the same, BUT, the pistons are different. the SOHC pistons have a dish where the DOHC pistons have a slight depression and 2 valve reliefs. You would have to grind a little to the lip of the dish on the SOHC pistons, and the compression ratio would be less by 0.7-0.9. Or if they are ok, just swap the pistons over, they are full floating pins.
