Finishing up the rebuild, and I'm trying to determine if I can use a set of intake manifold gaskets that I have vice buying another set. The sets I have are Felpro MS 90123 and MS 9980. My heads have the 1/2 size heat crossover, and these two gasket sets have a full size cut out for the heat crossover. Will this cause any problems? Do I need to get a different set of intake gaskets?
