? about installing P&P heads on stock engine

[1985GN]

if i got a set of ported and polished heads can i just bolt these right up to the stock intake and all? do i need to open up the intake to match the ports? do i need to cut a gasket to fit as well? does the stock exhasut manifold gaskets work fine? just curious about all this stuff.

The stock gasket will work perfect.I would at least port match the intake to get the full bennefit of the p&p heads.
