Yes, the lift is quoted with 1.6 rockers. A friend of mine was running this camshaft with AFR 190 heads. It ran real well and was easy to tune. It should also work pretty well with stock heads.

With unported heads, the extra lift won't get much and you'll probably have to change springs every so often. I'd go with ~.525" lift w/o porting.
Sometimes, you can get flow "stall" with too much lift for head characteristics. Local guy said he couldn't get much more out of 113 heads above .525" lift -- even with porting. XFI cams are aggressive enough, I wouldn't pick it unless racing for 1/4m times.

Enough that you'll feel it. Low enough that you'll either want more or feel you spent too much (with the install/tune). More satisfactions with head improvement.

I run a CC 262 in my L98 stock block and heads.
Truely the real way to get the L98 Corvette back into running and sounding like its heritage, is swap in a good cam!

Comps 503 cam would be the largest for stock heads. Right amount of lift with 1.5s and enough duration to give you a good lope and mid-top end power.
