Can't help with what you've ported into but can help with fixing.

You can use devcon to fill a hole a mate did when he ported through into the water jacket and it held nicely when pressure tested, just make sure you get enough in there behind so it can anchor for a stronger fix.

Polish the exhaust ports only, you need a rough finish on the intakes to create turbulance in the air.

Hope that helps
