Is it a flat tappet(lifter) cam in the engine?
Are you using the Valvoline Racing oil straight 30?(I think it says VR-1 on the bottle)

The building may be insisting on this cause that VR-1 has a higher zddp package(wear additives) in it which will help your cam and lifters lifespan

You should always follow the builders recommendations, especially if you have some sort of warranty with the builder
Yes it is flat tappet,however he is recommending just nornal 30W (just particular to valvoline); did not recommend anything regarding oils with high ZDDP. Honestly I think he may not keep up 100% with the current trends.
