Can't sleep and thinking - I know old men should not think, but I am curious what is a recommended brand (manufacturer) of valves for a mild, or maybe a bit more than mild, 318 with 920 heads with 1.78 Intake and 1.50 Exhaust. Strictly street daily driver. I just cannot see the cost of Ferrea and some others for a build of this type. Should I just go to NAPA and get whatever they have. Is there truly a difference in one brand to the next? Thanks to all for the advice.
