S4444

i have k04s, fueling, ERs, and 2.8 heads ready to go in my car after doing research on here about the heads... i also have an ASP turboback with test pipes and an X-1 intake.. i would port match the s4 intake manifold, however after speaking to some tuners the 2.8 heads might not be worth it on small k04s? id rather not lose the torque and i dont plan on building the heads to rev it high so what do u guys think, 2.8 heads better off on bigger turbos and not worth it on k04s? should i just ditch touching the heads altogether or should i save the heads and try running the intake cams without any headwork? thanks
