How do they perform, how much did they cost, and would you make the previous (longer) intake rockers as well?

what are you dreaming of now! and dream is the word? these are handmade mate for a racing engine and you can't even ride your knackered old nail! how much further from racing can a man get?

the CSA of each arm should have been very narrow and very tall rather like the elyptical wing on a spitfire. i trust it came down to manufacturing time and money constraints?
either way - a superb piece of engineering!

I have relocated the valves in my billet head compared to an OEM head. All valves have been moved slightly out from the center of the bore to make room for larger valves and sufficient flow around them. To make the adjustment screws aligned with the valves, new rocker were needed. Thats the only reason for anyone to make this effort. By relocating the valves I also got nicer gear ratio on the rockers. So maximum valve lift was increased by 1,0-1,5 mm! Good for performance - not so good for valve train life length. 8)
I do the design and mail the 3D CAD file to my royal machinist for materialization. He has machined this jewel to his brother in law. The billet head, rockers, triple clamps, rearsets, etc, he has done for me, came out when he blew his nose...

Taffy is it possible for me to ask a question without you jumping in and making a personal attack against me?
I told you that several times, it's getting old.
Dr C, thanks for the answer. I just wanted to know about the parts, not order some for myself.
