Long story short, I bought an engine off a guy (440) that was building it for racing 8 years ago. Its been along time coming, but I've finally got down to building my car to get it on the road.
The engine was way too aggressive (.562 / 296 degree cam), so I replaced the cam and valve springs.
This is where it gets interesting. When changing my last springs the cylinder won't hold any air (first flag). I could see that the valve wasn't properly seated. low and behold, the sleeve where the valve comes through the head is cracked. When I took the heads off I could see that the valve had hit the piston, bent the valve and cracked the sleeve (head).
i've been told that the heads can be sent out and repaired, but do I take the risk? Or should I just buy new heads (which I know are good) and try to forget this whole disaster happened?
Looking for any input to help me in this decision. Here are some pictures of the bent valve, piston, and cylinder sleeve head.
