Valvetrain question!!!!!!
would it be a ok or bad idea if i did supertech valves with itr valvesprings and retainer on a gsr head? its going to have Ctr cams or itr cams on the head running with a gsr block, p30 pistons. lmk ASAP thanks!!!!!!!!
the reason is because i only have the intake side itr valves. the exhaust side valves are b16, thats why i was wondering if i could do supertech valves on the itr valve springs and retainer.

Re: Valvetrain question!!!!!!
Might want to provide a little more info about the valves if you want a definitive answer from this crowd. Trying to google this, or atleast the spec differences on each part compared to the parts your replacing (lift,duration,etc.) might help too, plenty of threads on hondaswap.com about "mut-motor" combos like this.

Well the CTR/ITR red lines at 8400 right? To be on the safe side (since you'll be in the head anyways ) invest in better retainers. The springs should handle 9k.

Re: Valvetrain question!!!!!!
I would normally get keepers from the valve company, just to make sure they're compatible dimensionally.
If you're wanting to rev to 9k RPM, I would think really hard if you're willing to risk head damage by mixing and matching parts just because they're what you happen to have laying around.
There shouldn't be any problem using the Supertech valves with the ITR springs, just get the valves for the head you're using so you have the best chance of having the right seat angle, stem diameter, etc.

OP old parts are called OLD for a reason, if you want 9k, get good quality parts that have not been beat to death for 100k and up, and don't slap something together and have high hopes... it ends in disaster
