I have a 71 coupe that needs the valve seals replaced. The motor is not the original and it has an Edelbrock performer cam and intake. It also has headers with flowmasters. What I was wondering was, since I need the heads done, is there anything I can do to get more performance from them without spending a lot of money or is it even worth it? any help would be appreciated.
