roller rockers and solid roller lifters

The build up will be a 440 stroked out to 512 tunnel ram with a pair of demon 750( yes this is a bit excessive, but its what i have and beside it looks really cool) fender wall headers, 3500 stall, gears are 4.10 and the exhaust is 3 inch I'm wanting about 600 HP, I dont know what "bushed the lifter bores means, I'm still learning about some of this"

As for new rockers or not I dont have a preference as long as they are in good shape and not take a dump a month after I install them.

Well you're building a "Monster" aren't ya, good for you. My car before the Demon was B body with a dual 4 440 mind you not a tunnel ram.
Anyway what bushing the lifter bores is for 2 reasons. First, using bronze bushings, the lifter bore is machined out to accept the bushing and at the same time the bore center line is trued, something highly recommended before running roller lifters. The second reason is to partially close off the oil galley that feeds the lifters since you won't need all that oil that a hydraulic flat tappet would.

The reason I asked about new or used roller lifters is that I would never use second hand lifters without overhauling them first, replace the bearings and any other worn items. Therefore yer better off buying new.
With those gears, stall, exhaust and stroking you're definetely going in the right direction for your HP goal, I'm just a little warry the combo won't be very streetable.

We got a member on this site that goes by Moper, run your combo past him and see what he suggests.
