Magnum head porting for the beginner

Truly excellent job on the editing!! :):thankyou:

Excellent job all the way around! I just have one small criticism-How does a guy in the corner of his garage use stones (Kwik way or Sioux I'm guessing) for the very important valvejob. Honestly don't take this the wrong way , its a rhetorical question.

Seriously great work though and great thread. J.Rob
