Re: Valve to piston clearance on MMS 224 and other notes… Sounds right to me.
My 5.3 heads were milled at least .015 to .020
My 224 XE-R has .075 P to V on intake
I've seen my 224 XE-R spec's overlayed with the MMS224 spec's from a cam doctor, the XE-R was a hair more aggressive.

Re: Valve to piston clearance on MMS 224 and other notes… Can anyone recommend a website with a detailed write-up that explains in detail what all the different #s mean regarding cams (lift, duration, etc)? I'm a bit ignorant in that area. Thanks.
