Going Roller on my 340!! Solid or Hydraulic??? Pro's and Con's

It's been a few years since I've run solid rollers in a small block mopar because my life is all new hemis now. But, I'm starting a 4.125 stroke 340 for my 71 Ruster and am considering solid roller. Back before I got into new hemis and stopped building small blocks one of the main problems with rollers was aluminum/bronze distributor drive gear would wear out in less than 10K miles if you had decent oil pressure. are there cam cores available that work with normal drive gears now. Next question, has anyone run the MRL offset pushrod lifters on a 59 degree block with offset rockers like w2 or w9 heads? I'm curious how this holds up as I've got some heavily worked w9 and lemans w8 heads that I'm aching to make work on the 59 degree block.
