I think you should ship out your 243s for porting.

+1 on getting your 243s ported. There are a few good porters in the area or you can get them sent out on a core exchange.
I talked to Bob at PM FL why he coats the heads and his theory is that there will be less heat in the combustion chamber and coating the intake runners will provide a heat shield for the intake charge and also coating the exhaust will allow the exhaust gases to flow better. His ported and coated heads are only $1500. I know a couple shops around here would charge 2k-3k for ported heads. He's also the one who coats most Kook headers.
Also I found an article about it:
