Yes sir, they seemed pretty loose around the studs I placed ( only 3) for mock up. Noticed that they dropped down and could slide out of alignment.Also Mike (you probably know already) but look closely to make sure those 1009s don't hang over the bores at all anywhere.
Fel-Pro 1009's have a bore diameter of 4.410", a 0.060" overbore is 4.380" so you shouldn't have an issue like that.Also Mike (you probably know already) but look closely to make sure those 1009s don't hang over the bores at all anywhere.
The head dowels are supposed to keep the gasket in place and not allow it to move. If you are missing the dowels, or they are damaged and do not fit snugly in the gasket dowel hole, replace them. Please resist the urge to use any copper coat on the head gasket.Yes sir, they seemed pretty loose around the studs I placed ( only 3) for mock up.

Thought about some copper cote on the corners to help hold them in place. Of course when I did this I did not have my deck facing straight up...

Just a note. Double check your piston to head clearance with those reverse dome pistons. Are you using the open chamber rpms or the closed?
Here's a pic of an OE gasket for posterity...first head removal since factory assembly, '78 440. Same skinny slots even with the bigger figure-8 cooling holes.

Earlier blocks just had a round hole, but later 70's blocks had a larger peanut shaped holeLooks like the slits are more centered over the passage on the stock gasket than mine and I cant tell in the pic are the lower passages blocked off ( closest to header side)? Mine are...
Thanks Bean!
As 69Bee said, the later blocks have a bigger hole. (If you look real close at that gasket you can see the crud outline of the figure-8). The only holes at the exhaust-side of the gasket are for the head bolts, just like your fel-pro. For water, there are the slits between the cylinders, a big hole at each end and that's it.Looks like the slits are more centered over the passage on the stock gasket than mine and I cant tell in the pic are the lower passages blocked off ( closest to header side)?
