Meh. Those shims are going to be all mix-&-match once you start cutting valve seats, lapping, blah blah... MSG is on point. Those heads are worth way more as complete packages. Maybe repair, spruce up... I dunno. I'm amazed at people that are good at wheeling and dealing. I always get burned unless I pay retail for new shit, and I just give away what I don't need.

Noob question here: This engine has ARP head studs. Yesterday, I was trying to take the nuts off to get the heads off but they were really really tight. Much tighter than a wheel lug and much tighter that the old chevys that I worked on years ago.
I don't know what is normal for these engines. Do I get on it with a 6' cheater bar and go for it? |

Post mortum
A buddy said it might have been caused by detonation. To my untrained
eye, it looks like the piston just f'ing broke. |

Repairable?
As I posted earlier, these are Element Tuning big valve heads. As a noob, I have no idea how much it would cost to repair this kind of damage. The valves (-4) and springs are around $1800. Plus bronze guides.

I’d try sending an email to Headgames. I bet it is repairable.

Piston and sleeve look to be mildly annoyed for some reasons.

How many miles/hours were on this expensive motor? I don't ever remember seeing a piston in that many pieces. Yikes!

Good idea. I, myself, am not interested in keeping them. I'll probably put in the classified ads at a bargain price. Is it a $500 repair or $1000? It might be easier for someone (who know what they are doing) just to strip them for parts.

This failure looks kind of reminiscent of a high RPM single dirt bike engine. When they started going to 4 strokes for MX I saw a similar looking failures lot. Piston slaps around and breaks the skirt and wedges itself in cylinder and the rod beats it apart.
