My boss is very good friends with Danny Jesel, they are kinda over kill for me and they don't fit under the stock valvecovers. I think the head needs some machine work to fit them. Jesel is like 15 min from me, I have seen them they are a very nice piece. I coulda had them for almost nothing.
Any body know the difference in the Comp lobes and the rest of the lobes out there, Thunder, Futral, etc ?

 

Patriot makes valave cover spacers to fit them. Hell hook me up man Ill send mine back. I got the sportsman series for 640.
