Ported stock E7 or GT40 heads?
I have a 94 gt and im looking at trying to change up my heads. Im looking at either porting my stock heads or trying to put on some gt40 heads by myself. I'm wanting to do this as cheap as possible and I'm not sure which h would be more affordable. With the gt40 don't you have to replace the factory springs before you put them on because they're weak? And is there a thread or website that shows the right way to install heads? Im kinda new to working with heads
