 Anyone know the significance of fulcrum sled markings on stock 302 engine rockers?
I am cleaning, rebuilding a stock 302 V-8. I have the stock valve rockers which are a fulcrum design, no adjustment. I took all of them off on one side before I realized some are stamped with an "I" and some (very few) are stamped with an "O" They are not of equal number so they are not intake and exhaust. I don't know which ones go where back on the head. Anyone know the significance of these markings?
thanks,
