I have searched alot on here and found these heads in another thread. I am going to put some new ones on the L98 in the next month or so. I have ported plenum/large tube runners/hi flow base/AFPR/suspension mods. Give me your honest opinions please..I don't need any sugar coating... I would like to run in the 12's on just motor. I am planning on a converter and cam soon too, so if you have any input on what would work well with these heads please share
175cc / 56 cc chamber to bump the CR a bit for more power

195cc/ 62 cc chamber.Allows for future upgrading

Between those two, the second without a doubt. No sense saddling your 350 with small valves and small runners.
