Hi i was looking for some guidance on my impending mods. I want to put a speer pulley upgrade kit on. I also want to port my SC and port & polish my head,install afternarket performance headers and port match the headers to the head. Can anyone tell or guide me on everything i need to consider or parts i need to upfrade to make this work well? As an afterthought doing the porting work and aftermarket headers affect the remap chip that comes with the pulley upgrade kit? Any input will be gratefully received.
