Super & locks are actually 8 degree. Will not work correctly on any thing but super 7 retainers.
If your rockers are the self guided rail type. Lash caps won't work. They increase the valve tip diameter to 3/8". Rocker will be too narrow between rails.
Cheapest way out is to go with a +.050 pushrod and lightly trim the rocker rails for clearance. As long as the roller remains fairly centered on the valve you will be ok.
