Hey Greg,

Sorry to hear about all the issues. I realize you were supposed to have pushrod oiling, but the spray bars should be adequate, if there is enough oil volume. Do you know the spray hole size and quantity, and the restrictor size feeding the head?

I had a problem with number 1 and number 2 intake rockers on a Hemi not getting enough oil from the spray bar and it was turning the roller and valve tip blue from heat. When I calculated the total area of the spray bar holes, and compared them to the restrictor, they were exactly the same. Considering that pressure will drop over distance, it didn't have enough volume to maintain pressure at the furthest point from the source, so it just dribbled oil and didn't actually spray. I'm going to assume your spray bars are fed from the rear of the block, so numbers 1 and 2 are furthest from the source, and may need a little more volume to get a good spray on the adjusters. It's worth a look.
