I decided to replace my lifters because they are making noise, badly. Well I started working on it today and realized that I'm going to have to pull the heads to do the lifters, unlike most you can't go through the intake. Well I didn't realize this until today. So I'm stuck in the dilema on what to do with the heads when I pull them or considering buying new ones. I have plans to build a completely new motor next year for the T/A but this motor will go into another project. So from those with experience, is it even work doing anything to the stock heads? If I do replace them, any recommendations? This motor will be a cam only motor, no N2O or boost in it's future.
