Might be cheaper to buy a gm roller to be used with those factory roller cams. I think you use what they call " spider plate'' to hold down the roller lifer guides?
The hot cam number is 24502586 and goes for about $200 or so, there is the 350 ram jet 14097395 for about $150.

If you go Comp , you need to check with them and see if the gm roller is compatable , i think it is.
