2.5 heads on a 3.0!?
Posted: Fri Nov 18, 2005 6:40 pm
Before everyone laughs too hard the 2.5 heads have a couple of potential performace advangteges if they will fit a 3.0 mechanically.
1) smaller chamber = ess piston dome
2) smaller ports/valves = more material for optimum porting without welding.
The chambers are 5mm smaller but thats easy to alter. Custom pistons probably needed. (Ive done this with JE for ducatis).
Except for the chamber size is there any thing else to prevent putting 2.5 heads on a 3.0 block?

Now, how much are JJs group1 12v cams........
