where could i get my head ported its a 2001 tiburon and i would like to replace the springs and valves if i could find the stuff for it and what would be my gains and like the estimate for all of this stuff
Guys shouldn't be scared of DIY porting heads. I've done a few and it comes down to patience, common sense and research. Unless you are aiming for big power, most of the time just dressing the walls of intake and exhaust ports to remove irregularities in the castings then a few finishing passes with flap sanding drums will improve engine performance (performance doesn't mean 'power' but how efficiently it handles fuel burn and throttle response etc) Port matching on the intake side will aid throttle response if you're using a stock intake manifold but don't mess with exhaust port diameters unless you know exactly what you're doing - it can badly screw up your engine by having exhaust pulses over scavenge air/fuel charges from combustion chambers. Do your port work on a head you know is solid then let a shop handle valves and milling. You only need basic tools to do it like a power drill, a hobby rotary tool like a dremel and a few accessories like small grinding stones, flap and drum sander attachments and cheap rotary tool attachments.
