I'm going to keep everything as is with the exception of having them add a little lift.

Re: Hartge H23 cam specs
If this is going to be a regrind you cannot add lift or for that matter reduce the base circle without changing the profile.
I don't know what the final lift is because I can't read the doc. but if their using 1.5 as the rocker ratio its going to be way off.
On the cam pro data sheet it says the duration @ .200 is 112/113 respectively, these numbers should be in the 160 range.
Who is grinding this cam for you? If your in San Diego must be Jerry Cantrell? If you want a brand new chillcast semi finished blank to grind it on I will sell you one then you can retain the proper base circle without welding.
Now that I think about it He should still have a few M20 blanks left over from the '90s. Hopefully he is not still measuring with a BMW foot glued to the bottom of a Chevrolet lifter!! Got a good story about that one but I won't get into it here.
