Street Cruser

I dunno if he would do one for a /6 or not, but on the 360 magnum in my Durango I put a set of valve cover spacers on it. there's a guy on eBay that sells different thickness valve cover spacers for less than 1/2 of what (taller) Mopar performance valve covers go for, I bought a set and put them on when I put the 1.7 roller rockers on that engine.you will need 2 v c gaskets (not included) and he sends some longer studs along with them. Makes it easier to line up than finagling bolts thru a cover, spacer and 2 gaskets
(Hey I got them with a parts trade for almost free)
This guy does them for several Mopar GM and Ford V8s I'll have to look, the guy sent me a couple of his cards with them. His name is Dan "something" and he's out of Pa.
