Whats the deal with replacing intake cams for exhaust cams? Is it a case for swapping out the intake for the same size exhaust and using 4 exhaust cam gears? When ordering large cams, just ask for for 4 exhaust? When black beast snapped one I took notice, when he snapped another my build plans changed, loose vct bla bla bla, happily sacrifice mid range for reliability. UAS was doing it 13 years ago, didn't pass on the info as far as I can find. JWT RM5 are these solid as in not hollow?
