Help Climbing Hills - new head?

[hotrodalley]

i have a stock model a engine with a lightened flywheel and a weber carb. I am also running a 36% mitchell overdrive and an aires muffler. I am happy with the combination except for the fact that I am losing speed on hills. I like to be able to maintain at least 50 mph on the hills. The engine is also a babbit engine in very good condition.

Will a high compression head solve my problem?
