basically I'm looking for some imput on the heads should i port polish the 205's I have or go bigger, was just trying to give some xtra info to avoid those questions as i want to spend my money wisely to gain the best bang for buck
Depends what your overall goals are. Are you going to be going to a larger motor, eventually, plan on forced induction, or just want to stick with the stock engine size?
If you plan on a larger engine or FI, I would say go with the 225s. And with a Port and Polish, they'll work even better.
If you plan on staying stock bore, I'd say stick with the 205s. You don't need to smack the largest head you can find, to get good power numbers. It's all about building the proper combo.

good point nick i think for now i'm staying na maybe a lil spray but for 1300.00 for the port and polish and lighter vavles plus install for the afr's vs a new set of 225 tfs or 230 afr's am i gonna gain more with the larger stock heads or ported 205's and room to build on the larger heads?
Honestly, I think your best bet is to talk to a shop. If you're looking at a different head, you may even be better off swapping cams. Ed at Flowtech is a good guy to talk to.
