[DeTomaso] Engine Oil Analysis / Willow Springs Update

[Donny Williams]

Will your probably right, however valve float "Could" cause interference on 
a tight V to P clearance.... My understanding is he runs the piss out of 
this thing, that is why I brought up as a "Keep it mind".
Your also right about the header gaskets....   Those for me are obvious, but 
maybe not to others.   Another worth keep it mind for Dan.....
