Dan has his Offy valve covers listed at $158.99 - part # 5284. This is the same price that we started at back in 08. Last time we ordered over twenty and got the price down to $144. Offy did a casting run just for us!
The only problem was that some of the polishing from Offy was not perfect especially around the bolt holes. Also the cover has no provision for pcv - have to do that yourself.SS- Dan has got a nice write - up to help solve that problem.
Again, if we have enough interest I will call Howell Automotive, AAA marine, and Dan and see what we can pull off.
If you search Offenhauser group buy? You can see the play by play from last time also Dan Marvin is mentioned in the slanted network.
