That's the easy part. Having the tools to cut them out is another issue.

Did you have gaskets between the spacer and block as well as the normal Fiero gasket for the valve cover? If so - what gasket?

Yes, cork gaskets for the sheet-metal valve covers. If you put the aluminum spacer directly on top of the iron head, the different thermal expansion rates can cause leaks. You need something soft between them, to act as a buffer.
Also, my 3.4 V6 came with studs instead of bolts for the valve covers. The studs have plenty of room for spacers.[This message has been edited by Blacktree (edited 02-14-2018).]

If a person has to rely on other's mistakes to learn then that person has no sense of exploring or curiosity, he is just a parasite waiting to feed on other's misfortunes. That is sad!
I'm not saying you are a parasite Mender, I'm just responding to the author of what you posted.

Some more progress! Picked up my coated pistons today! A thermal coating on top and a super slick coating on the skirts. I have to weight match all of them now.
The rods are already matched so are the lighter wrist pins. Next, one of each of these components are going to the machine shop along with a set of piston rings
to be weighted to balance the crank taking into account the 2lbs weight savings on the rods and pistons. The crank is also getting knife edged.

If you don't mind benefiting from the experience of others, I'd advise you to change the orientation of the grinding 90 degrees so that you aren't generating stress risers in a vulnerable plane. Also, a smoother surface finish would be a good idea.
A belt sander with a 120 grit belt does a very nice job of that.[This message has been edited by mender (edited 02-19-2018).]

I agree with Mender. Those grinding marks are parallel with the wrist pin hole. That will encourage cracks in the end of the rod. You want the grinding marks to be perpendicular to that. Here's an example of what I'm talking about:

I don't mind at all Mender! As a matter of fact some advises from Will, Blacktree, Lou Dias, Fieroguru and yourself to mention a few have made me revised certain things on this project. I think that by the time I finish this project it will not only be mine, It'll be ours!
Your suggestion is very good but this picture was the rough cut only, they all will be polished and cryo treated along with the crank.
