My take on the oiling system crossover tube for the small block

Yes, all holes were opened up previously.
It’s a 76’ LA 360 block .030 over.
I’m using Sidewinder heads so they will have stock style oiling to roller rocker arms.

Neat heads.

You did not say how. you are oiling the heads.
Are you oiling through the cam bearing on number 2 and number 4?
Or are you making them full time by drilling into the oil passages?
