The other parts of the build that I missed. We recently finished the head for the motor and consists of..

- Faced/glass beaded.

- Race ported head specs and port matched to the inlet manifold.

- Standard valve seats removed and larger aftermarket ones inserted to suit the oversize Supertech titanium valves inlet/exhaust with single groove collets.

- Supertech valve springs with titanium retainers.

- New lifters.

- Stock cams.

 

 

Also finished of the surgetank set-up aswell...

- 3litre surgetank with x2 Walbro 460s inside, all factory lines removed and replaced with braided.

 

Have you conducted a very close inspection of those cam shaft lobes.

probably the sexiest looking barra I have seen. Oversized valves hey? cant say I have seen or heard of that being done on the barra before. Im sure it has been though, what sort of power are you shooting for to be doing things like that?

coz fg cams are known to have case hardening issues and can look pretty rough at low km.

Just what I observed from your images. Any signs of surface spalling will deteriorate very quickly with heavy valve  springs. You need to inspect the rollers as well. They have less surface area. 

 

just hate to see all that work and money end in damage.
