In my paranoia after buttoning up the timing chest I thought it may be best to check the pushrods again.
NOTE – If pushrod kit contains four different length pushrods,
the longest pushrod is for the front exhaust, next longest is the
rear exhaust. Of the two shorter pushrods, the longer one is
the front intake, the shortest pushrod is the rear intake.
and I found mine are different in size but are also in the correct position.
So... tomorrow its the timing light...
