I'd pick up a service manual of some and familiarize your self with the top end rebuilding procedure. Be sure to check valve clearances with the new head and cams. Likely the header will replace the cat so check to see if it would fit with the cat removed.

Took the old header and cat off tried to match up the head with the header an def not fitting the bolts are no where near close enough to even try and i just went an got the haynes for this model ill let you know progress as of now im putting the new valve springs an caps i suppose ( dont really know the name sorry) just following everything step by step
