Cruising in the autumn leaves....
Well, in one of the threads we had a few posts complaining about the quality of brand new parts. Well, for my buddies 440 GTX, we found some NOS (never used) Mopar Stage VI heads. These are from the mid 90's.
Well, guess what? they didn't fit on the block because the block dowel pin holes in the heads were mis-drilled about .080" too narrow.
So I had to exactly measure and figure out how they were mis-drilled. Turns out both needed to be elongated the same amount to ensure the heads would fit properly/ with the right alignment (elongate each .040" straight towards the edge of the head).
Here is my setup after making sure the head was perfectly parallel to the table, and level in both the X and Y axis.

Then it was time to use the exact size end mill to elongate the holes. This is NOT a drill bit as the side of it cuts as well. The setup takes all the time. Once setup is done, cutting took 10 seconds or so.

Perhaps I was more careful in measuring than I needed to be, but now the heads fit perfectly on the block!

The fenders look good.I picked up a better pair of front fenders for my 70 Charger and today started cleaning them down to metal to start fresh

That air cleaner came out sweet! Nice work!
I know all too well about hours long setups and then 10 minutes of butt time watching the machine do the cutting lolWell, in one of the threads we had a few posts complaining about the quality of brand new parts.
