When you put it together after you port match everything and or do some intake end to end adjusting which isn't unheard of to align the common walls... you can use four 1/8-in drill bits to align the gasket to the intake & to the head just as it was when you had it torqued and it will go back together the same for sure. It makes it full proof and when you do your Port matching to the intake you use those 1/8-in drill bits to locate the gasket and use a little tape as well and go to town
