I can't stress enough if anyone wants head work doing go to Pez at Racedna, or seek advice from him on what route to take.Not enough compression to get the most out of pro 3, in an ideal world you want 13.5:1 and race fuel and then you're running 260hp with the right head work and supporting exhaust and inlet setup ;-)
