i was wondering is the engine still non contact if the cam belt goes with the roller rocker conversion (higher lift ratio) I would think of doing this mod if its still safe!
The tuning parts list indicates with 569 cam (0.569" valve lift with stock rocker ratio of 1.76) the engine remains non-interference. Given that the stock 548 cam with roller conversion (1.8 rocker ratio) gives less valve lift (-8.5 thou) it seems reasonable to assume this combination will allow the engine to remain non-interference, especially as valve overlap is likely to be less with stock cam.
