Modifying my EF/EL 95DA head ready for super charging. Going to XR size valves Int 47mm Exh 41mm, stem size 8.68mm 11/32 and are double groove collet as far as can find out. Haven't found the length yet, anyone know the lenght or part number for quality after market stainless steel valves.

convert to single collet as they are better, use 351c valves and machine the heads down to the size you want. You will also need to look at changing the springs and possibly the retainers as well. Probably looking at around $500 in parts alone

talk to a good engine builder who deals with these motors all the time.

Thanks for the replies fella's. Talking to a engine builder that deals with these engines all the time sounds like the best option, I have looked at catalogue after catalouge and found nothing that matches, any one know of such an engine builder in W.A, They might also have some suggestions for a windage tray.
