1st thread - Stuck with a 307: performance suggestions?

For the most bag for your buck I will say headers. You will need some way to get the exhaust out before a camshaft consideration.

Before you go cam shopping you might want to pull a valve cover and let us know the casting number on the heads,if it has the original 307 heads and you are on a budget I would replace them with the 305 H.O. heads easy to find for very little cash and have hardened seats,for what you would pay for just the Comp Cam you could get a good grind from Summit with the lifters and new valve springs,I would recommend this part #SUM-K1103 should work well with your cubic inch motor and existing parts.Then get the headers with it.
