[Voyager]

Just reached 300 miles on my new KC 408 street crate engine.

Part of the instructions that came with it states; “on all aluminum engines it is necessary to re-torque the intake & cylinder heads after 300 miles & to re-check valve lash“.

Stupid question…I assume my cast iron block makes my engine not an “all aluminum engine” and therefore the above is not required?

Thanx
