I have an 04 yfz 450 with a Vertex 480 (98mm) full FMF exhaust hot rods crank and connecting rod, dropped a vale and had to replace valves and head. Went with Kibble titanium valves and had a used head laying around so went that way. camshaft and head didnt play well together and now i will be replacing the camshafts and head. was thinking about upgrading cam while im in there and was wondering if stage 1 hot cam is prefered with the big bore. any advice would be appreciated. thank you!

Best thing to do is pick a builder and let them do the head. They’ll tell you what cam to run.

My personally choice is Rage.
