Hello, I haven't posted much but have kept eyes and ears open getting educated . Well, I've narrowed my choices down pretty much too DART Iron Eagle 165cc- or 180 cc but not sure which I would be good with. I have a sbc 350- stock rotating- with a mild cam- 204 in. and 214 exh. with lift of 420 in. and 442 exh. but have 1.6 rockers that move it to 442in. and 473 exh.
Would the 165 cc be getting restrictive in the upper rpm range? Rarely break 5200-5500 rpm . Right now I have the stock smogger 624 heads from 1976.
I can get the 165 cc about 2 bills less but will they not be enough head if I go to a little bigger cam in a couple months? Summit has a cast iron head at 165 cc that supposedly is cast by DART for them cheaper but still- too small?
Have studied this but no actual experience with after market heads so will gladly accept any ideas from those who know more than I That means pretty much everybody Thanks to all. Sorry, forgot- have 350th auto and 3.73 gears out back.
