IMO get the complete kit from Ferrea
It comes with severeduty valves , titainium retainers , dual springs , chrome moly locks , spring cups.
Crower valves are heavyduty not severeduty which is a must for 100% reliability not 99%

 

if you are staying NA, get the lightest valves you can find, lightened nitrided stainless steel......DPR used to offer valves specifically for NA duties, supposedly the lightest on the market that were not titanium...dont forget, you might also want to look to see if you can get these valves in a flat-faced configuration for a bump in c/r

i took the recomendation of my engine builder (dyno spot racing) and went with rev stainless steel valves

did flat flace for some more c/r

i am putting the engine in tomorrow, i will let you know

I wonder how much that ferrea valve package goes for?

ferrea is good stuff!

 

does ferrea have a website or who carries them and who has teh best price
i kinda like the upertech valves portflow carries anyone heard of these
also what about stock itr valves i can get a set or 16 for next to nothing
but i heard that itr valves are weak
thanks

itr valves are great

lots of people with built motors run itr valves

they should handle 220+whp and 9.5k rpm runs

i would go with itr valves. only reason i didnt is because they are expensive

 

so will itr valves it in a stock gsr head? i thought i read somewhere that the diameter of the stem was smaller than that one of the gsr? is this true if so how is it made to fit?
thanks
chris

 

should fit

i havent heard differntly that they never would fit

call and engine builder and ask them

who is building your engine anyway?

 

ferrea =
ferrea price =

 

my thoughts exactly
i can get some itr valves with like 12k miles on them for like 50-75 bucks i think i am gonna go that route
