using 1.7 rockers with the f cam

[dastang2]

can i use 1.7 pedestal rockers with a set of stock heads and f cam with .512 lift. as of now i have to use .060 of shims under my stock rockers on stock rebuilt heads and a stock rebuilt block. i used these heads on a different motor without shims but this motor needs shims. not sure if the block has been milled only or both the heads and the block. i am not using these heads though. i am using thumper heads. anyway. can i use those rockers with my cam even though i have to shim my stock components that much
