Piston is OK. Valve, Guide was ripped out of head, Rocker arm junk obviously the spring and retainer. It's all fixed up. Just waiting on a head gasket.

I thought it might be the guide or seat. Glad it's fixed, go get'em!

Was the valve to guide clearance to tight? Making that must steam your egt's must expand that valve a bunch.

No. The spring was the first to go. Then retainer. Then side load on guide. Then valve touched radially. Then bent valve. Then rocker.....

Not sure why spring broke.....

What springs you running? Did the dyno let go of the engine at any point? I've broke a couple PAC double springs from the dyno letting go.
