Thread: help with modding

wow sounds like alot off stuff to get to just switch over to a different type of fuel. How far can you go on rockers and headers?
In the safely modding your 3800 it says with rockers you can drop a pulley size and with headers you can also.
Whats better modded stock rockers or roller rockers. i know the rollers are easier on the valvetrain. but is there much difference between 1.9 and 1.95? Im gonna go with rockers. but still thinking of intercooler later. just wish they were alil cheaper.
