    Ouch!

    I am kind of curious why you wouldn't work through the bottom end with the piston to valve contact? If it were me, id pull the pistons, clean them up and take them to a machine shop to get tested for cracks. I would be more worried about that than the head really... you could drop $1000 into the head and slap it on there for 500 miles and have that piston that looked like it took the initial hit to the valves fail. Now your at square one only worse this time.

    And you aren't really limited to finding a head in your area. There are 4-5 on here right now for super cheap. Sure it would be a few extra bucks to ship it, but they aren't as scarce as you'd think. And it would be much cheaper than a full rebuild and you could look into the rotating assembly. Think about how hard those pistons actually hit the valves...

    Your already 2/3 of the way pulling it down, may as well do the rest for reassurance. If anything your out a set of rings.

    Edit: FWIW, I know this is a COMPLETELY different scenario as far as motor type. But a few years ago I built a big bore stroker motor in a quad. The first time around (yes there was two times rebuilding this) I tested and reused the timing chain, it was within spec at the time. Took the 11 hour drive to Glamis and on day 4 of 5 out there the timing chain stretched and skipped some teeth on the cams, had piston to valve contact. When I got home and tore it down the piston (Wiseco) was cracked in 2 places around the inner skirt near the wrist pin, also took out the lower rod bearing as well and trashed my freshly ported and polished head that was built to the tits. Ended up adding another $900 to my already $1700 rebuild for not going through everything and reusing 1 stock part on it, and the upgraded chain was only $80.

    Ive learned after that its better to be safe than sorry... And these guys are spot on with do it right or do it twice!
