im building my GSR head with supertech valvetrain minus the valves & blox HSL camshafts. I will be using skunk2 STD comp valves. Someone told me that i would have to get the valves cut? or something iuno i wasnt really paying attention and im confused about what he said. If that makes sense to anyone can you help explain to me exactly what that means? So im guessing i cant just install them right out the box then right?

It's recommended to have a valve job performed anytime you rebuild a head that's seen lots of abuse or mileage. Specially when you install new valves. Having the valves and the valve seats cut, installed height checked and guides inspected (valve job) to ensure the valves seat properly and clearances are correct will make or break your build.

i appreciate you giving me good info, and not flaming me for not knowing. but what does it really mean to have the valves and vavle seats cut though? lol im still confused about that.. lol

The second vid made me feel like I was cutting valves in a gay club.
But good info though. The first vid is cool as hell!

Question. Why skunk2 valves over oem itr valves?

im curious to know why you would pick itr valves over the skunk2 units? i heard a few locals say the same but the locals here would rather run ctr cams over skunks pro series cams because they make more power.

Made me laugh out loud

well as its been covered alot in a different thread OEM valves are better and hold up just as well.

so why spend 600 when 3 will work better.

Im sure hes not and Im sure he does. I didnt mean to imply that he was gay. I just would have picked a dif song is all. It didnt seem to match the video. Nothing against gays either!

Ive always used oem valves except for one time and the results were disastrous. I see alot of people use aftermarket valves and was just curious why they choose aftermarket over OEM. Im sure everyone has their reasons,and thats fine, I was just curious why thats all..

yungkhmer

thanks alot guys, your imput is greatly appreciated !!! The reason why im using skunk2 valves is becuase i can get them brand new for really really really really cheap!.

yungkhmer

wait if i were to pick up brand new itr valves would i still need to have the valve machined? The reason i ask is becuase its OEM, so shouldnt it just fit right in WITHOUT machine work?

b20vtech

New valves, Old valve same concept, needs to be machine to match up and seal to the seat for it to work!

yungkhmer

cool thanks man. would it make more sense to have the machine shop put the valves and the rest of the valve train in apposed to me doing it myself after i get the valves cut? i know how to put in valve springs and retainers just not valves. but i got buddys who could do that for me, im just trying to save a little money.

and if i do just have the machine shop do everything, exactly what do i tell them? " cut these valves and make sure they dont leak? " sorry guys i still am kinda new too all of this and thank you for your patients helpin out this newbbb (me) hahah

Red_Army

most shops include assembly of the entire head. valves, springs, retainers, cams, so forth.
but yes it would make more sense. they have the tools for everything and probably do it often. it's also usually included in the cost of the valvejob.

hah no. you'll want to give them angles of the seats and they'll do the valves to said spec. but they're smart they'll help you figure out what you need.

thanks ehonda for the link.

yungkhmer

but... i dont know the angle of the seats?...hahahah

b20vtech

tell them to do a standard 30/45/60 angle valve job then it should work or send it to me for a custom profile valve job if u like.

yungkhmer

okay ill see, alot of people are telling me to go local to this place called action auto parts in shoreline,wa.
