I have a 68 mustang with 302 69 heads that I ported myself.I seem to get mixed reviews when asking about installing 1.90 intake and 1.60 exhaust valves.Some say the ports are the real restrictions and the bigger valves aren't worth the money.Engine has basic hop-ups wiend x-llerator intake 650 holley dp comp cams magnum 292(518L [email protected]) headmen headers roller tip rockers and flat top pistons.Car works Ok but I'd like to go faster without breaking the bank(aluminium heads)or installing and building bigger motor. Any suggestions? car has run a best of 13.69 at100.94
