hello i am new to the camaro world

i am looking to get a good set of heads for my 350tpi that will help give me a higher rpm range

i am also looking for a strokerkit and intake manifold that will let me keep my tpi set up and again that will allow a higher RPM range

also looking for tranny rebuild kits and a good set of 3.73 or 4.10 gears.

also are there any rear seat delete kits sold for these cars

thanks for any information.
