NO.....the valve seats will be ruined in short time. If you take the heads in to a machine shop, they will install hardened valve seats in your heads, then the unleaded gas will be fine to use. Don't forget, you need to add Zinc to every oil change or you flat tappet cam and lifters will be junk. Put in a roller cam, change your fuel line to braded stainless, and you will be every bit as good as a new car. Enjoy.
