Chevy Rocker Arm question
Who has done the chevy rocker swap on a 300 head? Am I correct in reading other threads that this is just a unbolt and bolt in application to get some additional lift?

Im also looking into doing the cheby lifters. I guess my biggest concern is the wear on the valve guides. How hard is it to put new guides in while your doing the lifters, or is it more of a project then someone who has to ask should take on?

Not having done it myself I woud think that you would need to take the head off to drive the old guides out and replace.

I did the GM rockers before I did the cam swap. It is actually a seat of pants improvement, and a great low buck mod. Even with a cam, I have no coil bind. It is that easy, except with mine, it made the rockers adjustable. Some engines will allow you to torque the adjuster nut all the way down.

I have about 2 years on the swap with all good. The cam is from Oregon Cam Grinding(274 adv duration/.518" lift). With cam and lifters, $137 to my door. No mods to the head. I wish it was decked and ported.
