My brother and I swapped out the head on my L20B for a A87, everything went smooth but the engine has a bit of a tick that speeds up as the revs go up, the bottom-end was fine so we excluded anything wrong with that... rod knock ect...
The valve lash was off so i Redid it to specs (cold) the tick is not as loud but it still very noticable.
It does have an aftermarket cam, specs are only slightly higher than a stock L20B cam.
Is it normal for cammed motors to tick, and is it safe to run it like that? It runs well, but the tick is kinda annoying... Sounds like a Toyota.
