guy's, i have a aluminun Duggan 250-292 head. it uses the shaft mount rocker system. what application did the rockers originally come from? tom

From what Mike Kirby told be,& I told you,these parts are not available anymore & were made specifically for that cylinder head.
Not borrowed or used from any other engine.

just trying to tap into other minds. they sure look like sometype of stock application. tom

The are several companies that make performance rocker shafts for both small and big blocks GM and Furd. In that the SBC is similar in spacing to our sixes perhaps something could be adapted. I found several listings on that auction site. Just a thought.

i should have posted the pics. here they are.

They look like MOPAR service package 1.6 rockers to me. The construction and adjustment make me think that. They were once available for the A, B/RB, and slant six, although the B/RB had offset adjustment screws if I remember right.

I had some shaft-mounted aluminum roller rockers made for my Furd 300 crossflow 12-port cylinder head. Harlan Sharp in Strongsville Ohio made them. I took them blueprints and a sample cylinder head just to look at. They did a sweet job - bronze bushed fulcrums, offset roller tipped ends, etc. I even asked them to anodize one set orange and clear-coat the other so I can tell them apart. I am happy with the way thet turned out. Pricey, yes, but I'll let you talk money with them.
Good luck with your project

Walt Skoczylas, the head of the Portland/Vancouver Ininers Chapter is running a Duggan aluminum head on his Altered Roadster. At least I think it's a Duggan head. You might look Walt up in the Inliners roster and send him an e-mail or call him and ask him what rockers he's using.
