Headers & 90 degree oil filter

If these were so bad than why did direct connection and mopar performance both remake them and sell them . Also to the person who said that the oil flows by the header pipe to fast to pick up any heat how do you think a transmission cooler works in reverse. I do want to agree there is some restriction but never heard of any one blowing a engine over it or i think mopar would of stopped using it before 1970 and don't think dc mp would have sold it , this 90 can also be made to flow vere good by just drilling two more holes in the bolt for a total of 6 or even 8 hole witch is the same area as you oil filter center hole and you can drill or clean out the casting were the bolt go through and to the filter.the only restriction after that is the flow rate of the oil filter your using. Also to end these 90 degree filter units are use even to day on some model mopar v 6 and 4 cylinder car that turn 6000 rpm with no problem . Look at old post about this i see people going both way so to each there own . Thanks to every one for there opinion.
