Re: Which Head Would You Pick?
Why do you feel the 185 woud provide more torque?
Solid rollers are planned because hydraulic rollers have extremely lazy major intensities (50-60°), and require very soft springs and light valvetrains even to make it to 7000. Frequently they have lifter induced losses even there.
Additionally, on road courses the solid lifter will handle more rpm before float on missed downshifts. For drag racing it allows shifts at 7500-8000 rpm.
Prior to emissions laws, all serious performance engines--Boss 302, Boss 429, L-88, Z-28--had solid lifters.
