yep and it was a BBC ? NOPE sbc chevys do not have lifter bore angle problems .some lifters were floating around that were junk . i built many sbc with flat lifter cams . but sooner or latter you going to have one bite you in the ass do you feel lucky... if the engine had a good history .not of a cam bore angle to crank .or lifter bore s then you may get away with a flat lifter cam with low spring lbs .big flat lifter cam and bigger valve springs low oil splash at idle that is when things get to be fun. i done many them as well and there are things that can be done to help them live but a roller cam is by far better way to go newer block come with roller cams .so you could just save the money build a retro roller kit for you older bbc or pick up a mark 6 bbc roller engine
