68 340 motor - x heads : the five spacers with bolts between rockers is it the two wide ones on either end with the three narrow in the middle OR two narrow spacers on either end and one narrow in the middle. Wouldn't be asking if I could find a decent pic - I think whoever rebuilt this last had it wrong. Book states I should have "three short bolts and two long ones - the three short bolts go on either end and one in the middle" I think he meant spacers, not bolts (all the bolts are the same size) This is from "How To Rebuild Small Block Mopar Engines" page 135.
