Hi all.
I would like anyone to please give me advice on what I can do to my 1200GX head to get more pep out of it.
It is currently a standard GX head.
I would still like to keep the head reliable.

I am thinking of only match porting and cleaning up the ports of rough edges.
Maybe fitting then A14 valves if my budget allows it.It is also going to get a 276 cam.Thanks

Match porting and cleaning of rough edges is a good idea. I think the valves from the a14 are the same size as a12, but the a15 has larger valves,someone please correct me if i'm wrong. One thing to consider when porting a head is the position of things such as water or oil pockets or galleries as you don't want to run into these.

That is why I want to do only a mild match porting and cleanup inside.
As it is a GX head, I do not want to mess it up.(Waterchannels,etc...)
It is not going to be done by me.A mechanic is going to do it for me on a flowbench.

Can anyone please give me advice on not hitting anything like waterchannels,etc....?
Is it possible to maybe leave the GX head standard and only add a 276 cam or will it not be much of a score only with the cam.I have read that the GX head is already good enough as it came from the factory...
