I have the following ported GX cylinder heads for sale. [I will try to post a picture or a link to pictures.]

Valve Train Pieces:
I also have used titanium valves, with smaller 7mm stem diameter, in the following sizes: 33mm exhaust; 37mm and 38mm intake. $10 USD each. [I have every size of stainless steel valves too, but rarely do I have sets of 4 valves. With these titanium valves I have about 8-9 valves in each size.]

2 sets of stock bushed rockers, polished exterior, $75/matching set of 8.

[If you want to purchase springs, retainers and cups in a set of 8, I will give a discount or ship them for free.]

These small items are not expensive to ship worldwide. Peter
