I picked up a 1974 350 with a .068 cam (the guy said) my question is would it be beneficial to swap out the stock 5C heads with a set of 62 heads off of a 68 400 engine ?
welcome gm,You'd gain CR from 7.6 to app. 9.0:1 as well as the bigger exhaust valves. Will they bolt up? Yes.. would you benefit from using them? Yes IMHO you would.
+1 It would be a benefit.

another thing you might benefit from is a gearing change. if you have 280 or 300 gears your car will be sluggish off the line with that set up imo.i would look at 343 gears.
thanks I will be going through everything and can definatly use some advice in each area
