would # 48 pont heads fit?

Which if any would be the best for my 76 350 Pont. #48 ,47, or 16's ? Would the gain in H.P. be worth it ? I have 6x4 now . Thanks ! They are 68/69 heads !

Depends on the rest of your combo. Are they stock pistons? What camshaft are you planing on using? 6x-4s can be good heads on a mild build. Need the rest of your parts and your goals to give you a better answer.

I have a stock 350 2brl that I'm changing the cam and intake to E/b perf. intake w/q/jet ,eb #2157 cam kit ,and timing set. It has dual ex. w/flo/masters and 308 gear. I was just trying to figure out if it woud be worth it to change the heads while I was this close. I'm not trying to build a race car ,I just want to have some power when desired !!! Thanks

GM put the #48 heads on 1969 350 HO, 400 Ram Air III and 428 HO engines but it has never been explained why GM put #48 heads on the 350 CI engine that has a 3.88" bore. They are excellent heads to use on 400 and 428 engines that have a 4.12" bore. The #48 heads have large valves with screw-in rocker studs and they flow well when used on 400 and 428 CI engines that is used as a daily driver. My 1969 Firebird 400 had #48 heads, HO exhaust manifolds, Crane solid flat tappet camshaft, 4-speed and 4.33 rear gears. I had consistent low 13 ET / 100-105 MPH.
