I was cleaning up my stack of V4 parts and noticed that the F2 heads are almost identical to F1. I have some damage on my F1 camshafts and I wanted to know if anyone attempted to fit F2 heads into F1 engine. Same for the oil pump - I have two pumps and two oil pans. Looks like a bolt on upgrade with nice OEM oil cooler setup. Any information appreciated. I will be tearing down my F1 soon to do the main bearings and crank bearings and I want to know your opinion.
