I realize a lot of this stuff is trial-and-error, but I also realize that whatever I do has probably already been done, so I have to ask... I'm about to convert my '70 Maverick 250 six to an aussie head and header setup. The engine has 66000 honest miles--- good compression, can probably go a while before needing a rebuild. I have a newly rebuilt 1.14 throat Autolite two barrel from a '67 Mustang 289 that I plan to use for the carb. I've already switched to electronic ignition. The car has front disk brakes and an 8" rear end from a '77 Mav with a 2.79 ratio. It has the C4 Auto tranny. I'm looking for a moderate power increase to use the car as a daily driver, and with gas prices going up, i'll probably keep the rear end as-is for now. I don't want to have to go into the bottom end just to change the cam, though that's the obvious answer. I know I can have my rocker arms re-radiused to a 1:1.6 ratio. For about two and a half times as much, I can get roller tip rockers. Are they worth the extra $ for a daily driver? I don't mind spending the $, if there is going to be a real advantage to the roller tips, but I don't know how much of the valve train I have to replace: Oil-through rods? Springs? I may be looking for more performnce later on, but it may be three years away, and I don't want to spend the extra now if there won't be any advantage. Any thoughts?
