I have a G series in my coupe, F22b2 block and H22a head. I am getting ready to do a timing belt, head gasket, head studs and water pump. Now my questions are:

What head gasket do I get? F22 or H22?
Headstuds?
Timing belt
Water pump

I am assuming I use all H22 parts but wanting to make sure before I go an start ordering ****

I have tried searching and for some reason I came up with nothing but K series parts for sale and other random b/s lol. Thanks for any and all help in advance.
