Larger valves...

do you really need oversized valves?

if i'm going this far into building it up why stop? you dont think with stage 3 cams and a port polish larger cams would be worth it? everyone that i have talked to said they would be more beneficial than even the port and polish as a honda head is already free flowing. i've just got money burning a hole in my pocket and gotta spend it somewhere, so why not?

i talked to erik from eriks racing and he specifically told me that he doesnt get any hp from using oversize valves on N/A applications, only FI

well i plan on putting some nitrous in the future....

But i've heard you can't go over 0.5mm oversized if you are going turbo....and 1mm oversized for n/a apps only....hmmm

after doing some research, talking to individuals, i've decided against the port and polish and the oversized valves, not worth the money and the gains wouldnt be noticeable enough for a honda. bummer

yeah i was about 99% sure you wouldnt get significant gains out of oversized valves... i think the port & polish is worth it though....

peace

well, from what i read, the most improvements are at the combustion chamber, cleaning up the valve seats mainly. check out the old timer .com pretty informative.
