If I put a mild cam in the car with an new intake and 750 carb do I have to do anything with stock heads or will I have to upgrade to new heads. I plan on a set of headers as well

I will not be racing , only want a engine with more guts than my 350.

Depending on the cam you get you may have to change springs but overall there is no need to change heads when installing a mild camshaft.

Stay below .500" lift and you won't have to do a darn thing...105 more cubic inches is going to give it more guts than that stock 350
