Your very right.
Ive got the 1252 and 1254 retainers to consider.
Gonna use the 1110 spring, maybe the 1111 spring.
509/280 mopar solid cam
This is my budget but new small valve 318 heads and I have the new oem valves, did the 3 way and a small back cut on the valves.
Kinda hard to find aftermarket single groove valves that are not costly, the 2.02/1.60 sets are dirt cheap since there so common.
