Is a hydraulic roller setup really worth it on a 350? I'm trying a couple dyno 2000 combo's for my dad, and he mentioned rollers coming up with far more HP, and I put a combo togther with a set of 64cc, 250cc flow Brodix heads ( the first heads I found a flow chart for so the first set of heads I could 100% match in the program ) and between hydraulic flat tappet and hydraulic roller, hydraulic roller makes about 50 more horse, but does it in real life?, because by the numbers that I put in the program and hydraulic rollers, it comes up to 435 HP @ 5000, with these brodix heads, a .440/.442 lift cam and a set of long tube headders.
