Finally hit the track with my sons new engine

Good question: when the relocated pushrod hole didn't hit water I guess no sleeve is needed.

I've gotten into the habit of sleeving EVERY small block Edelbrock head I port. I tube both the bolt holes and pushrod holes so I can kiss the tubing. The straight wall on these heads needs pushed over badly. I use JB Weld on the tubes when I install them and Splash-Zone epoxy inside the port after the job is done.
