just finished going through a big headache at the machine shop with some aftermarket valves i had ordered for my motor.
i have a 00' b16 head and when the valves were going to be installed the exhaust valves did not fit . the stem was to fat and didnt slide into valve guides. all the intakes were fine , so i measured them and and intake and exhaust stems were exactly the same . fuking gheyyyy ... but w/e .. i called company i bought them from and they told me to send them back for full refund ...
heres my actual question ..

i am debating weather upgrading the valves is worth it . can the stock B16 valves hold up??? i am not intrested in flow ,or light wieght **** ... i just wana make sure that they will not bend or mushroom or anything like that .

its going to be a high HP B20/vtec on boost ...

i think i might be going ahead and just putting stock valves back in with my new dual springs and retainers and calling it a day .. but i wanted to get opinions on the reliablilty of stock valves on boost .. pushing out anywhere from 500-600HP

oh and i plan on revving to 9k maybe a lil more .. not sure ...
buddy of mine is reving his (same setup w/ stock valves) to 9500 all day ... but i just wana see what the "honda-tech" community thinks of doing this ...!!!

stock valves can do amazing things,

stock valves are fine
i make 500+whp on my fully built lsvtec and the valves are about the only thing stock in the motor.

thanks for input guys .. i have heard mixed things from different people (people i consider to know wtf they are talkin bout)... and some say stock valves are enough and some say that boost can be realy hard on valves ..especialy exhaust valves and that they should be upgraded....

riceball: where do you rev to???
