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.]

SOLD JB Racing roller tip aluminum rockers, all in 1.50 ratio. Set of 8 for $280 USD.

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

Titanium valve spring retainers for larger 32mm outside diameter dual springs. Retainers $15 each. Springs, $10 each. Spring cups with aluminum spacers for the head spring seat area, $10 each. [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
