Is there any way to figure out what kind of cam the PO installed without splitting the case? The reason I ask is since I need to clean/rebuild the carbs I want to make sure they are set up for the cam. Is there a trick or am I SOL? FYI this is a 2.0 with what I am told are 1.7 heads. The carbs are Weber 40 IDF's (not 44's). I have a Compufire and SS heat exchangers. It was running like a spotted ape until recently because of grunge getting into the carbs. The fuel filters looked like they had a little poop in them. I digress. I believe the PO bought the webers and put them on right out of the box. Just looking for some advice (as always).

Is your crank puley degreed and can you see it?
If so remove one valve cover. Then pick one cylinders intake exhaust valves. Hand crank slowly until you note the intake to just begin to open. Note how many degrees before top dead center it is (TDC). Continue turning (did I mention it must turn in correct direction) until it just closes. Note how many degrees after TDC. Do same for the exhaust. How many degrees were the intake and exhaust valves open for? Also note, this will not be accurate due to valve lash but can get you close...
