Where to buy 1998 4.0 on ranger heads?
How much can honestly shave the heads?
Can you purchase the heads with the exhaustive ported?
Can you purchase them rocked rollers?

Morana racing has what you are asking about: http://www.moranav6racing.com/category.html?CategoryID=32

Are you locked into a 4 liter limited racing class?

If not a 5.0l swap can be less expensive with better results, and, "there is no replacement for displacement"
All "power improvements" are all about increasing the amount AIR flow thru the engine on each RPM
Turbo/super chargers, cams, valves, porting, even Nitrous, its all about the Air amount
Which is why, "there is no replacement for displacement"
