318/340 ps bracket the same?EDELBROCK HEADS... HELP!!!

wait a minute there.....you should have the 70 and up timing cover...the timing marks are on the left side.....that's about the only difference on the timing covers but the brackets MIGHT be different cause the water pump is different for the '69 and older because the inlet in on the left side where the '70 and up have the WP inlet on the right side of the motor.
