I'm planning on porting the head on my 98 12valver. I tow heavy and want the most from the "ole" 12'r. My main problem is exhaust heat. I've been told that porting the head, changing the cam and water/Methenol inject will cure the heat problems no matter what.
I'm thinking of going with Piers stage 3 head, and new cam
Please comment on this theory.
Also, I've been told that water and steel make rust. "Don't use it" This service manager at a local commerial engine service place said that propane is better. It'll cool without the rust problem. Your ideas, experiences here too please.
