A 327 has more torque & good for mods & a daily driver. A 302 is a higher rev engine to make hp & temperamental. The 302 heads have bigger ports & maybe valves. Maybe mix & match?

Well the 327 came with double hump heads with 1.94 intake valve when I bought it. It has a bad valve so I planned on using my set of l31 vortec heads, goingjjn with a single plane( maybe dual) intake and solid roller cam valvetrain I already have some full length x frame headers which I plan on using too

If you make it a 302 it will like higher revs and have less torque. I wouldn't suggest it for a wagon. I'd stick with the 327 it better if you on a budget for sure
