I have skunk2 dual valve springs, do i need to use different cams with these springs? or is it perfect fine to run ITR cams with them?

Will running these springs on stock ITR cams affect anything in a negative way?

I'd like to take her to 9k comfortably.

Thanks

 

Perfectly fine.

 

Thanks!

 

Same setup Im going with. according to jeff evans GSR cams give better midrange but ITR has slighty better topend, I would say if you plan to rev to 9k ITR is the better choice

 

from what ive heard, ctr intake cam with itr exhaust cam is the way to go with oem cams...but what do i know, i only have experience with itr cams and have nothing bad to say about them..

also, ive got crower springs w/titanium retainers.

 

how many miles on the titanium retainers

 

run zinc in your oil to help reduce wear and maybe a reinforced timing belt even just the gates blue belt to help. you should be fine at 9000 just keep in mind that qith the centrifugal force of the roatating assembly if you bang the limiter a few times or hard at 9000 you may actually see a few rpm higher. I learned that from datalogging at the track 9000 limiter saw 9200 rpm. don't get too lost in 9000 rpm as a goal your power band and gearing should really determine the limiter

 

about 10k. I change the oil more frequently than is probably necessary, and don't drive it too frequently. it has taken almost 10 years to put that 10k on them.

 

Thanks for the input! my goal is to build the head with mostly the best oem honda parts. only exception would be the valve springs, valve guides, and cam gears. Surprisingly brand new oem itr valves are cheaper than gsr valves, same with the valve springs.
