[QUOTE="CV355, post: 16287238, member: 181885"] 4v C-heads (Navigator) had the split exhaust port/divider, which required drilling with some blocks for coolant flow. Excellent for FI applications, but you have to port the hell out of the things to really see gains. I compared the flow numbers to that of what the TFS 2v heads were projecting (in early 2009), and went with the TFS heads instead. Sold my C-heads, waited until July 09 for the TFS heads to come in, then continued. [/QUOTE]
