Question on new heads

[Ian Ranchero]

I have a 67 ranchero with a great running 289. Has performer edelbrock intake and 500 cfm edelbrock car and long tube headers. 3-speed top loader and 3.25 ratio in rear. I have a full howards cam kit I am excited to put on, nothing crazy with the cam, fairly mild. My question is; I have been told i should purchase new aluminum heads when doing this but how true is this. Can i benefit from keeping stock heads and go forth with the cam kit? I really cant afford aluminum heads and can barely afford to have the kit installed at this point but i am really wanting to do it before winter hits in a few months. Thought? thanks guys.

Although you would benefit from a set of aluminum heads because they will flow better cause they will have bigger ports and valves but With a mild cam you will be fine with your heads. Maybe have them ported and maybe a little bigger valves but as is you will be ok.

Thanks Tos. Will i still be able to feel a good bit more power with just doing the cam kit?

even without the aftermarket heads, you will feel an increase in power, and right where the cam manufacturer indicates. one thing you might do after you change cams is to upgrade the carb to a 600 cfm model, it will serve you better than the 500 cfm carb. but again even this upgrade can wait until you are ready to do it.

remember everything you do needs to be done as a systems approach, but you will find this out as you go along.
