Heads & Headers
What sort of hp increase could I expect from a cylinder head swap and long tube headers? I'm thinkin about probably the Gt-40 heads, or something comparatively priced

probably about 50 hp, but it will open your engine up so the other mods that you do will have more effect as well. i suggest looking into a new cam as well. those 3 together may give you 75+ hp
