no
everything is a basic bolt on, take everything off your 22R block, timing chain, timing cover, head, and intake
keep your exhaust manifold, or use a header,
put a 20R timing kit on that 22 block, a 20R timing cover, a 20R head and intake, use 22R valves if you have a machine shop that can open those ports up a bit, but the stock 20R head is fine
if ,well more like when i do it again, i'll open up the valves to 45and 37 and use a .440 cam instead of the .460
my purpose for that?? shorter stroke of the valve in the guide, granted thats only .020" but
