I'm considering a pair of GT-40 heads for my 1978 351W. I know I'll have to drill out the head bolt holes to 1/2". What other mods will I have to do to make the mod work?


Will my Edelbrock Performer 351W intake manifold bolt up to the GT-40s?


Will my Hooker headers also bolt on?


Thanks for your inputs!


Mike
