98Camaro2s

Just got a 1998 Camaro SS LS1, has about 212,XXX KMS.
Im new to the LS scene and wanted a simple Heads/cam/intake/exhaust setup. Can anyone assist me in parts I need or if any gas anything for sale? Im thinking of probably going with the Brian Tooley Stage 3 LS1 cam, with trick flow heads, and a borla exhaust. Any other mods that I would need? I know KMS are on the high side but it has been serviced by GM its whole life. 17k In receipts and everything that has been replaced or done is factory (OEM).

Thanks for the help!
