My AMC bus heads arrived from Hoffman Machine today. They are excellent!!!!! (IMG:style_emoticons/default/smilie_pokal.gif) They were converted to 914 2.0 Spec. The old LE 180 style before the new CNC heads.
Now comes the question part. I guess I forgot to ask for the vent tube modification. My question is DO I need vent tubes? I am going to building a 2056 with stock 2.0 FI. Attached thumbnail(s)

I find them helpful. Need = no, want = yes. They'll keep your valve covers from leaking. Get a pipe thread tap and drill/tap the boss yourself. Not too hard.
