Get the jims steadyroll part 1827 , they are a bushing lifter no needle bearings to screw everything up, i am changing to these i run woods at the moment but there are a lot of big builds using these they are pressure feed at roller, i use a thayer 3 stage pump, its like the SS pump well SS is like thayer since he came up with it first, its a three stage, should be fine on pressure, i have a 116" was big at one time haha, so im going to get the jims i have the pushrods.net quick install these pushrods are the best , they make for wall thickness, fueling sells these rods also , and they just came out with their billet covers nice for room so rods dont hit pushrod tubes, i run woods tw9bg cams so not the nicest on lifters but love woods cams , i still think the simple TW8BG was the best dang cam out thier low overlap and just pulled hard but quick ramps so a little noisy. so if you chose non bushing lifter id call steve at GMR performace he knows lifters and has what use to be the SS premium , he knows who makes them and what the deal is with them.
