Can I just buy a complete engine gasket set for my 86 350 to install my Vortec heads, intake, and valve covers? Or is there a difference in the older gaskets and whats needed for the Vortec stuff? I know the valve covers have center bolts so should I have the gaskets with no holes around the perimeter? Also, is there somewhere I can get a bracket for the trans and throttle cables since the stock bracket wont work? Is there anything else I should know before starting the swap?
