The checking pushrods didn’t appear to make contact but They are 3/8 and I plan to use 7/16 on the exhaust so I marked the block where it didn’t match up with the openings on the heads and opened those up.

I also turned the block over and checked it see if the valves got close to the cylinder walls since it’s on a small bore but as you can see in the pic with the valve fully open they weren’t even close.

I then traced the cylinder bore with a pencil on the heads. The only concern is between number 1,3 and 2,4 cylinders, as the chamber is right on line. Since I’m using a 4.380 head gasket it should be fine but I need to look how the gasket sits on the head to be sure.
