That is how I have always run my 235 and 261 motors. The 55-57 235 blocks for example, you can pull the side cover and plug up the two drilled bosses for the steel line that runs from the back cam bearing to the head and run a line from the oil filter output to the plug on the side of the head that will feed the rockers directly. You have to use a line from the oil filter that is the same size as the stock output line or you will put too much oil on the rockers. The benefit is that the rockers, which are damn expensive to have rebuilt these days, get clean filtered oil, and a steady supply. Interestingly enough, back in the day the stock line behind the lifter cover frequently got clogged and the aftermarket sold kits to divert the oil filter oil to the head as above. You may be able to do the same with the 228.
