Priobe, I think you have made the right decision. If you take care of the pushrod issue, I think you will be OK.
If you ever change, check out
www.garrettmachine.com. He has billet rockers that will replace your DOVES and let you use your DOVE stands, which most agree are pretty good. If you want to buy the very best, his home page has the DOVE replacement and then look under his Products section where he has what might be the best shaft mount FE rocker system I have ever seen. His stuff is not cheap...the rockers are about $1,000 and the whole system is about $1450. They sure look strong though. He says they can handle 800lb pressures.
Good luck with your motor.
