Advice on cams for 9a..regrinds or kr?

How do chaps

My 9a is running on piper regrinds of standard 9a cams with 264 profile

Engine has done 4.5k miles since full rebuild with p/p head and balanced bottom end

Timing is spot on and k-jet has been adjusted so its not getting lean at high revs

However problem i'm having is that engine dont like reving past 5.5k :dontknow:

Could my regrinds be at fault?

Would i be better of with kr cams?

Or is there some other possible cause, fueling, tight engine…?

Any advice aprreciated

you ight want to check the valve timing

valve timing is spot on

alright mate, I'm no expert but the lads on CGTI with valvers all swear by KR cams, or modified KR cams.
