A lot of cam companies masters do not differentiate between intake or exhaust specifics,it's just a master to choose for either lobe,one companies "fast" lobes are likely slow by another's anyways. you really need the .100,.200.300 specs as well to get an appreciation of ramps,most companies now do lifter diameter specific grinds to allow for a decent rate.

Sorry, I meant 74. Both the 198 and the crankshaft I intend to use are 74. I have a 79 cylinder head so that must be where I erred in my post.

OK, then you are fine.
