Did you also port/blend the water passage opening in the block? There is a large mismatch at the block to the oil filter adapter housing.
I have a sohc oil filter housing on my dohc. It seems to work well enough, oil filter clears the mm k member. I also need to block off the bypass on the coolant crossover tube and on the thermostat housing. I don't run a thermostat on the car just a restrictor washer.
For the coolant passage behind the water pump I turned down a 1" piece of aluminum round stock into an interference fit plug and then drove it into the hole with some gasket shellac to help seal it up. Then in the back of the pass side head I drove a new freeze plug to block off the hole.
Fewer leak points and less to go wrong. Win win on a race car. Might even get lucky and improve cooling effiency by a few degrees.
