Generation IV External Engine - Can these L92 Heads be fixed? ((PICS))

04-28-2012, 06:02 PM
I am buying a L92 block with 60K to build for my C5. The heads are off the same block but the problem was that it dropped a intake valve and damaged the piston and chamber. So they just changed out the motor. The damage did not get into the valve seat at all.

So I need to know if it would be easier to buy a used set or fix the one damaged head and run them. They will not be ported just cleaned up.

From the pictures I would say so. I have seen a lot worse than that get repaired. Next question is the cost involved repairing the old head or getting a new one.

A piston break apart?

Those don't look to be ported so may be cheaper just to grab another than repair.

That's my thing. If it cost anymore than $200 to fix I'm better off buying a another set.

get another set. sell thos off for whatever can get from em. maybe a vj can fix em and some grinding in the chamber to smooth the rough spots. perhaps someone on a budget can use em.

I would be interested in buying the set u have to play around with to help off set the cost of new heads you could keep all the hardware just intersted in bare heads.let me know

If only one is ruined I have a single one that matches your casting numbers in good shape.

How much? And is it the same casting?
