you need to provide more info bro

With stock compression, the HP gain would come from the bore and hone you should get when installing new pistons. Even that wouldn't increase power much over stock, but an older motor isn't going to produce the same maximum HP as it did brand new, so the benefit will depend on how well the motor's running now. The rods and pistons, at stock compression, would be more for handling the stresses of higher HP from other sources, such as a small turbo or an increased redline. IMO you should get a valve job when putting new pistons in, getting both sides of the combustion chamber sealed up real well.

Indeed. What else do you have done to your engine? Goals besides the desire for more hp?

usually people use eagle rods and vitara pistons when running forced induction. I would recommend replacing the pistons and rods if you plan on boosting in the future

my bad on the no info part, but its a SOHC zc vtec, nothing is dont to it other then an exhaust, headers, and cold air intake

well Vitara's are for FI. And you dont need forged rods unless your going FI, because you wont break the HP threshhold on the stock ones.

It would be next to pointless to do it unless you plan to boost the engine, like said three times before.

oka what about valves, valve srpings and retainers and a cam, all skunk 2

you would be wasting money to put those in your car without a turbo setup to accompany it later.

as for building the head.... dont waste your money. unless you planned on doing an all motor d build (waste of money) it will get you pretty much nowhere compared to a b series swap or a simple turbo kit on what you already have.

my advice is do some research on the sight and learn how all these parts work for and against you before you start throwing money around.

If you had the head worked on and got oversized valves, they would help you make more power on the top end. Just replacing the valves with the same size won't really make more power. Tighter or dual valve springs are one step toward raising the redline, ultimately making more power. The tighter springs also increase rotational resistance, decreasing hp somewhat.
