Weber intake with a set of 58mm, Top of the line rockers, start with Jessel or T&D. Sharps are next with the complete roller rocker, not the bushing one. Ersons would be after these. You get what you pay for. You have to get amchine work for some of the kits, top ones, the others are bolt ons. How big a cam is going in this motor? RPM range? The smaller the cam, the easier it is on the valve train. Any single plane manifold with port matching is good to 7800 rpm but your motor is not nascar. Match the intake, heads, cams, compression, and exhaust to run best in what rpm you want. Build a tork motor, the hp will come with it. Bigger is not always better. You could buy Cracker's motor
