Removing TFS inner valve springs to break in Comp camshaft.
Hi from England.
We're building a 460 with TFS Power Port heads (with 'inside' valve spring locators) and a Comp XE274H camshaft. Comp calls for us to remove the inner valve springs when breaking in the camshaft however, without the inner spring the bottom of the outer spring is no longer held secure and centralised. Is it safe to run the engine in that condition at around 2500 rpm for 30 minutes?
TIA

That won't be an issue with break-in; remove the inners.
