I am about to rebuild a 390 in my 62 Monterey. The manual says to loosen the bolts in sequence two turns at a time. It however does not say what the sequence is. Does anyone know what it is?
Here is what I found in the manuals I have . Starting at the No. 4 cylinder , loosen the right valve rocker arm shaft support bolts in sequence , two turns at a time . After the bolts are all loosened , remove the valve rocker arm shaft assembly and the oil baffle plate . Starting at No. 5 cylinder, follow the same procedure on the left valve rocker arm shaft support bolts . THIS PROCEDURE MUST BE FOLLOWED TO AVOID DAMAGE TO THE VALVE MECHANISM .
Firing order numbers should be on top of your manifold . Hopefully this helps , keep us informed . Thanks Wayne
Thanks for the quick reply Wayne.
Just to be clear, start from the rear on the right head and move towards the front and then from the front on the left head towards the rear.
Thanks again.
