bigger vavles
i was reading on thumper page that the way to get more airflow on heads is to port them , or to get a bigger vavle, but if you go too big on the vavle the air velocity is slow, so to make more air speed you need steeper gear like 4:10
so here my question. i have 4:10 gears, and i going to get a head package combo 2 from thumper, but he leaves stock vavles for low end power, since ima be punching the throttle down the strip most of the time, and never riding in streets i figure i can use a bigger vavle since i have 4:10 Gears.
well where can i buy bigger vavles, i think stock is what 1.46 where can i get like 1.94 or something near there

RE: bigger vavles
i got 1.94/1.6 ss valves with a back cut for flow on my 70 302 heads and made a difference in power....they had 178/154 valves..if i remember right..with ya gears id go with bigger valves..id go with bigger valves anyway..the stock runners are like 124 or so..so they need all the help they can get...
