Engine build… just because I want to…

I seriously doubt that that big slice can go anywhere… and regardless, it would be very easy to drill and tap the port from the bottom… couldn’t go anywhere, even if a bomb exploded!

I think it’s a very cool, period Correct mod.

I don't think such a big piece of metal would go very far either, but if it starts to move it will create filings that will be sucked into the engine and scratch the cylinder and the piston.

@rene4406 could you repost the picture please

Yes… that’s what needs to be done on my head too…… Doesn’t take much to do that

But I leave that up to the next owner..

When you do it, just thread the insert and not the wall of the head. Drill through the insert and thread the entire hole. Drill the hole in the head so that the shaft of the bolt is snug but doesn't thread to it.

This way you can tighten the bolt in a way that it clamps the insert to the head and you are guaranteed that the bolt hasn't bottomed out in the insert.

If the tip of the bolt sticks out a little into the port, that's ok. It won't adversely effect anything.
