Hello gents and thanks for your time in advance.
I just installed new GN1 ported irons on my 87 and I am getting ready to start installing the stock headers BUT I am unsure if I need to use RTV or (not needed?) if so what brand of RTV do I use?
Also, If RTV is needed on which side do I need to apply it (on the head surface itself or on the header surface?
