I have a 1998 k2500, and I'm starting to heavily think about performance upgrades. I've gone through most of my suspension, steering and brake components and finally made it here. I've already done a full exhaust system, egr delete, and a blackbear baseline tune. I've been thinking about having my heads ported and polished (thoughts?), and installing the best cam (whatever that may be) and really just looking for more ideas, and potential cam suggestions. Not looking to rebuild my motor at this time though.
