same as u could normally. doing heads will not affect how stout our lower end parts are. getting their heads, however, will increase compression from 9.4:1 to 9.5;1, and allow more air to flow in and out of the cylinders. this will allow for more hp to be made w/ the same amount of boost being run. doing exhaust will reduce backpressure, and may bleed off a little boost, maybe a pound max. u will make a lot more power, however, because the motor's efficiency will go up tremendously.2001 Arctic White Firebird<br />More mods than I\'m allowed to list!
