I cover this in my book, probably not as good as it could be, However all modern engines use the full flow filtering system, and it just makes sens. Especially with the cost of building these engine is so high, might as well take advantage of this system. All the engine I buld back then had this modificatio,. One person removed the filter with out removing the grub screw and destroyed the bearings in just a few minutes in just a few minutes.
