Im building a 438 stroker in a Dart Sportsman block and the lifters i have will not work' which or comp cams #87879-16....Im running the Brodix 201 head with T&D shaft mount rockers....These lifters would work fine except the oiling predrilled hole in the lifter is running the same way as the oiling galley...I looked through where i took out a back plug & have like a 100 thous of the cutout in the center of the lifter ' but the problem was i noticed the predrilled oiling hole was dead center of the oiling galley running along the galley insted of being on a 90 degree...Comp said they had a brand new lifter they could order that were pretty sure it would work' but i know soimeone out there has ran into this problem....these 201 brodix heads are the canted valve heads that have to have 1 center and 1 offset lifter....the part # above were offset but will work in the svo block only they said....Anyone know of another lifter or brand that will work with my combo......Thanks....
