You can put Oldsmobile 350 heads on an Oldsmobile 307, if the 307 is 1984 or older. It will take some work but it can be done, I know for a fact that it can, because my 307 has 350 heads on it. It runs great. I'm not sure about the cam though.

Can you put 350 rocket heads on a 307 Oldsmobile engine?
Yes you can
Your 1985 Olds Tornado has a 307 engine can you upgrade to a 350?
Yes you can upgrade to a 350 but only if it is an Oldsmobile 350 and you will need to use small block olds toronado intake from a 307 so you will have hood clearance-you may need to enlarge ports in intake to match 350 head ports but probably not much. You can use your 307 heads on the 350 but I would put bigger valves in those heads before I used them with a 350 and porting would not hurt if you want much performance. The Olds 350 will have a lot more power stock than the 307
Does the Oldsmobile 350 heads add more compression to the Oldsmobile 307 motor?
Most 350 heads had 64cc combustion chambers. On pre-86 307's, it would bump you up to 8.2 (from 8.0:1). post-85 307's it would get you 8.4:1. On post 85 307's you'd have to change your intake to either the 350 intake or an A4 aluminum. The ports are tiny on post-85 A5 intakes.
Will 307 heads bump up compression on 1970 350 block?
it all depends on the head chamber volume of the 307 heads and the 350 heads that are being replaced. if the 307 heads have a smaller chamber volume then yes, they will bump up compression.
What kind of heads will fit my 350 Oldsmobile?
Any GM 350 small block head will fit. It all depends on what you want the engine to do. Stay away from aluminum heads if they get to hot they can warp. If we are talking about a genuine Olds engine, it will not interchange with any other GM 350 engine. There are some pretty good heads available from Edelbrock.
What is the firing order for a 1983 Oldsmobile v6 cruiser?

Can you tell a 350 rocket engine by sight?
You can tell an Oldsmobile V8 when you see one. You can also look at the casting numbers and engine suffix code, both of which will tell you that it's a 350 Olds rather than say, a 307 or 403 Olds.
Will a 1988 307 Oldsmobile motor fit with a 1992 350 Buick roadmaster transmission?
Yes
Can you use Oldsmobile 307 5A heads on a Oldsmobile 403?
YES, the 5A heads FROM A 307 can be installed on a 403. The307 heads are a BETERR choice than the 67 to 72 Olds 350 heads. The 307 heads have similar sized intake & exhaust ports to the stock 403 heads. The 307 heads have a much smaller combustions chamber at arounf 67cc. This alone will raise compression to around 9.5:1. The only down side is the 307 heads have much smaller valves. You really must get larger valves installed into the 307 heads. The stock 403 valves will fit with some machining (of course) and you'll have a high compression 403. Get some port work done while you are at it & a little polishing too. Buy a new intake & have it machine & port matched to the intake & a middle of the road Lunati cam. This will result in a 403 producing around 330 HP. I know it works because this is exactly what I did. Enjoy your Olds, Mark
