Tubing the gallery with a twist

Mopar performance solid lifters are about the lightest non composite lifter on the market, or were. I run solid rollers with a shallow oil band and feed holes to the rollers, I also run full groove mains and my clearances are around .0021-.0024 range , a 'c hair' tighter on no.1 main. My oil psi never dips below 28psi at idle FWIW. I buzz it into the mid high 6000's rpm on average, no tube...no mods.
