kool...

Talk to Fredness, he's the 3.0 V6 guru he'll have any info that you made need.
Rogue Roller lifters and performance tuning will be what I would recomend. I haven't used them yet but from what I hear and have exp. on someone elses ranger it the best thing you can do. Also you may want to add a K&N O.E.M direct replacement air filter and change to 10W30 motor oil. Also change your exhaust but keep the stock size pipe. This will give you an 18 to 24 MPG's over the stock 14 and 17 Mpg's. Changing the roller lifters with the heads out will be even easier considering that you're changing the heads to begin with because rogue roller lifters the heads stay in the truck when you install them. Here's a link where you can get them: www.rogueperformance.com . They carry the roller lifters I mention plus a whole host of other mods and parts you would like.

I will tell you the 3.0 is a very easy engine to take apart. I think it took me about an hour and a half to take the drivers side head off of my truck with air tools. I agree with the roller rocker upgrade, but if you're taking both heads off call around a machine shop and see what they want to port and polish them for you and do a valve job.

Yep it's already a roller motor, but the stock lifters aint that good. Plus I agree about the porting and Valve job completely. The polishing is reallly up to you. here's another link you might like: www.moranav6racing.com . They even carry stroker kits for the 3.0. Plus If you do decide to have a machine shop do the entire Valvetrain you can have them shave the heads if you want.

He didn't mean roller lifters. The engine already has those. He was talking about roller rocker arms. Those with a good port and polish, cam swap from Morona V6 Racing, and a good tune, would net you a lot more power and better fuel mileage.
