1G Lifter Options?

[Dreams2memories]

Noob here. How's everyone doin? Anyways, currently building my first 4g63 6 bolt and gonna begin work on the head this fall. I'm going with GSC parts and I had a few questions as far as the lifters and rockers. Will oem rockers and lifters handle 600+hp? If not, what are my options? Appreciate any help.

while your head's out, do this: http://www.dsmtuners.com/threads/4g63t-head-oil-port-mod.341028/

search for engbldr at ebay for some lifters.

stock rockers may still work fine.

I already know about the oil port mod on the head. Thanks though. I can't go with the stock rockers knowing that they or may not be fine under this power level.
