Do your lifters have the ability to pushrod oil?

If they do, 8 pushrods for the intakes with holes in them would very likely solve your burned pushrod woes.
I did consider that approach but unfortunately it won’t work with my combination for two reasons. 1- my oil galleries are tubed to shut the oil off to the lifters. And 2 - I don’t think my lifters have the ability anyway. Thanks for the suggestion though.
