The good thing about that engine is the valve seat is parallel to the piston. So the only thing that happens when the piston hits it is it slammed back into the seat/guide.
Any other engine and all there would've been a catastrophe.

sure. non interference engine they call it. thought I would point it out just in case changing springs wasn't enough. changing the cam profile to steeper slope will shorten the time the valve is held open. if you end up needing a valve job, well you'll know soon enough. good luck.
