Alright, so here is what I have so far. Jdm h22a with eagle rods, and brand new oem type s pistons. I want to get some cams, but if I did, would I need "racing" valves, or can I just get new oem valves. I know that I will need upgraded valve springs and retainers, but I didn't know about valves. Also, the guy that had this motor before me ran it low on oil, and it scored the rockers a little bit. Can they be polished out, or do I have to get new rockers? Thanks, Dave

you generally need stonger valves or the stronger springs will break the neck of the valve.

Alright. Does it matter what kind of valves I get, cuz there is a bunch of "racing " valves on ebay. Do you think my rockers will be find with the scores on them as long as it isn't starved of oil again?

i believe honda valves are stronger than most people give them credit for. the disadvantage to them, however, is the weight.

rebo0t

^^ i agree.

turbo_d

So what kind of valves should I get that arent really expensive, and will still be strong enough, and light?

Try doing a search, remember to search for archived posts aswell.

There is an unbelievable amount of information stored on here at your disposal if your willing to look for it

98vtec

id you are going to replace the valve, expense should not be a factor.

My two top choices are Ferrea and Supertech.

note to self:
when doing a build, dont just buy it because it is cheap. if it is what you need and what you want, and its cheap then by all means go for it

stock valves are AWESOME, dont waste your money on aftermarket valves.

it sounds like you have bigger issues anyway, i would take the head to an experienced machinist specializing in honda heads to look at those rockers and the rest of the head

turbo_d

so stock valves will hold up with aftermarket springs, retainers, and a set of s2 stage 1 cams?

definately

turbo_d

would it be worth the 100 dollars you save to get these springs, and retainers

rather than the skunk2?

So you are going to pay for the guys motor if a stock valve does brake?

I'm not questioning the strength of new OEM valves but a valve that is 100k+ old put under extra strains is a bad idea imo.

Am I right in thinking OEM valves are manufactured from two pieces?

how many stock honda valves have you seen break? i have never seen any and i have been in the game a while.

are you going to pay for his motor if an aftermarket valve breaks?

Of course not. I'm not assuring him that they wont brake though

this discussion is pointless, there are plenty of motors that make 800+whp using stock valves and there are plenty more using aftermarket valves.

i have made 280whp on stock valves in my all motor h22 and never had any issues. i have tried aftermarket valves in the past and actually had them fail where factory valves havent, so i can say from first hand experience that factory valves are AWESOME

NAH2B

and if you have plenty of money to spend on aftermarket valves that arent going to do a thing for you, then i guess it wont be a problem paying to have the valve guides replaced when you find out the aftermarket valves wont work w/ your worn guides

turbo_d

I dont know how many miles are on this motor though. Does it matter? I was going to get a three angle valve job, but you've got me convinced that these valves are pretty strong. Are the valves going to be too worn if they have 150k on them?

NAH2B

the mileage wont affect the strenght of the valve. when you have a motor w/ very high miles on it the valve stem and guide are going to be worn. the stem will have some play in the guide and there is a max. measurement for it. i have run heads w/ very high miles on them and the play was excessive for hondas standards but everything worked fine.

for what you are doing w/ a mild pressure spring and mild cams i would not be the least bit worried about the valves or guides. i would even feel 100% comfortable using old oem valves in a race motor as well. i would clean up the valves, have them checked to make sure they are not bent and probably have a oem valve job done.


you should be much more worried about the condition of your cam journals and rocker assemblies/rods since the motor has been run out of oil in the past.

PrecisionH23a

Stay away from anything on eBay. Look into crower, skunk2, or supertech for valve-train.

turbo_d

Does anyone know anything about the obx cams? I found of obx stage 2 cams, and I was wondering if that would be a good pick, cuz skunk2 is like 500 dollars. It says on the auction that valve train upgrade is needed. Does that just mean springs and retainers, since I am using stock valves? Thanks ,David

PrecisionH23a

Did you not read what I just said?

OBX is cheap ****.

turbo_d

I have heard a lot of people on honda tech say that the obx cams are pretty much just a copy of some other name brand.

PrecisionH23a

Then why are you asking us since you've already got your mind made up? 90% of OBX stuff is name-brand copies but they are absolute crap as far as quality goes.

People have tried OBX cams, they destroyed the rockers. Look elsewhere.
