I think that looks fine, the only change Id make is to install the 1.6 rockers on the intake and the 1.5 rockers on the exhaust valves. that 2.5" exhaust may be slightly restrictive but I don,t think it should cause a problem.don,t forget that combo require you to keep the rpm range above about 3000rpm and below about 6300rpm to stay in the torque curves peak, so trans gearing and rear gearing and perhaps stall speeds if its an auto effect the combo! if its an auto equiped car a 3000rpm stall will be almost mandatory
