They do *not* like a restrictive engine. These work best on engines with ported heads, free-flowing turbos and mufflers, good intercoolers.
Well, I have all that except the heads right now, but those will happen later. My Mahle 3.4 pistons have valve reliefs from the factory, are they big enough to clear the lift on those cams?

At this point im leaning towards just throwing some 964 cams at it until I do the full top end. Just seems silly to pull the engine for the clutch and not throw something on the engine at the same time.
