Also.. are your econo heads, long valve or the
standard.. they use different rockers.. MP messed
up and sent one of each heads.. took me a while
to figure out why I couldnt get the geometry right
on the standard head with the long valve rockers
on that head.. both were meant to be long valve

I want to say they are the long valve but I'll have to check with the shop. Do you happen to know which PN's go with which? I don't have access to any of the old catalogs and while I was of age back when this stuff was new, I wasn't paying attention.
