I started a separate thread in the event it wasn't worth the effort........my apologies.
I did check the gasket vs the exhaust manifold..........the openings on the manifold match those on the gasket.
So it would be beneficial to match the exhaust ports of the head to the ports of the manifold?
No. The opening in the head being smaller than the manifold will HELP with anti-reversion of the exhaust. Keep the exhaust ports like they are.
