Piston damage?
I'm doing a head/cam swap and just got the head off. Today's surprise was seeing that the valves have been hitting the Pistons. I thought I knew about my engine (it's a swap) but I'm finding its not what I was told by the seller. I am putting ported 243's on there, but have no idea what heads were on it (the casting numbers are ground off). I'm assuming they were milled. Should I fly cut the Pistons or hope it'll be fine with the new heads?
