Not many cams work with 1.6 rr's and stock lt1 heads but a hot cam or cc305 might but you will have to double check ptv clearence

both of those cams should work with stock heads and 1.6 RRs. but the clearance under the valve cover will b a issue

you HAVE to run vette aluminum head guide plates from GM with those rockers. the intake valve is off center from a regular SBC head and all aftermarket guide plates will cause intake valve side load. Now a stock LT1 has valve reliefs in the pistons. you can run high 230 duration with about 560 lift with out too much PTV. Now intake centerline and LSA also come into play But on the lower side say 228/230 540/560 lift cam you will be fine. SO your basically in a boat to use a baby cam Just to be able to run those rocker. if it were me and io already had them and i wasnt going to pull a head to check PTV. id run them on a stock cam stock LOW MILAGE? springs. or run the cc304 cam and run 941 springs and retainers. CC305 cam Might work But again i KNOW these 2 combos will work without any head modification to fit a longer/heavier spring in the pockets. or having any PTV issues. hope it helps.

Duration has FAR more to do with PTV clearance than lift. The valve is hardly open at the top of the piston stroke anyway.
