Hi guys,
Im in the process of planning some head work and looking at the available options in the way of a 1mm oversize valve set for my RB26 head and im hoping someone can shed some light on exactly what is available and from where. Ferera, Nitto and Naprec are the only brands I have heard of, are there any others worth looking at?
Also on this subject, what other components in the head will need to be changed to facilitate the larger valves?
Thanks
