Guys, I'm thinking of scrapping my simmons injection and going AFP. Anyone have suggestions on Cylinder head vs. primer port injection, installation tips (RV-4) do's and dont's, etc?

I know first off, the cowling could be affected, intake, hoses, mixture/throttle cables, to start off. Not to mention plumbing pump, filter, etc. Just trying to see if it's worth the $3,000 and the headache.
