Get a pushrod checker ($20) and set up a dummy lifter and measure PR length. .060-.090 preload is what you shoot for on LS7 lifters otherwise use manufacturers specs.
Make sure you PROPERLY set the wipe pattern for the new rockers. Otherwise you will see increased valveguide wear.
Good luck with the swap:D
hardened 7.4 pushrods,melling oil pump would be almost a must cause the oiling systems are shitty as fuck, definitely a good tune ?? and maybe some gears depending on auto or 6spd......headers exhaust lots of factors to get full potential out of teh cam ..my buddy had same cam with stock heads and intake with full boltons and 4kstall and 373's and is runnin 11.49 consistantly all day
