Not uncommon to have jets that are way bigger than needed if the hi speed bleeds are too big and I too was at 99`s w/ .037 hi speed bleeds so I went w/.028 hi`s and brought the jetting down to 84-92 (ft. p/v) and now it rocks. What size are the hi`s now...........Another note; can`t pin holley jets w/any accuracy due to the taper unlike others like maxi jets and maybe BLP which are numbered to size not flow...........
