Reply to "351C factory heads, can valve guide cracks be repaired by complete removal of the iron guides and pressing in thick-wall bronze guides?"

Is the cracking on the top of the heads a serious issue? Couldn't he press / machine out the guides, and then remove the thin cast material? I can't see how that cast housing adds A LOT of strength.

I would be worried about the cracks inside the port, though. I wouldn't want a chunk coming off the intake side.

I'm just asking, to trying to learn.

Thanks.
