Do you use Hyrda Rev kit?? AFR suggest me this kit to reduce chances of valve float associated with rpm 6000 or higher.. Is this really work well?

GhostZ

Nope....my old setup saw float but that was more due to weak springs than RPM's. I haven't seen any float so far with my 987 springs.

Black97

Are CC 987 springs good? u happy with them?

Black97

I got 195" AFR heads ,and AFR official website suggest me to change walve springs with AFR High pressure valve springs and hardened retainers with Titanium Retainers for using hyrolic roller camshaft..
AFR vs CC?? Is it better to use Comp cam titanium retainers and cc springs ?? Or AFR's titanium retainers or springs??

-Aslo a question for size of the parts:
CC Titanium Retainers 1.430" O.D. but AFR's hardened retainers are 1.450" O.D. If I change AFR's with CC titanium will be a problem??

Give Cam Motions a call, tell them your whole setup and theyll make you the best custom grind for your setup. 225-926-6110.

Black97

yea I will contact with them for the custom grind.. Anyone have any idea for which valve spring is better? AFR's or Comp Cams? Should I change my AFR's springs to Comp Cams' ??

Black97

any suggestion????

Depending how radical the cam is(how much lift,etc) the CC 987 spring would be fine...Or if Cam Motion does your cam, I bet they'd recommend a spring for you to use.

probabily I will use 230/242 544/576 114 LSA Nitrous Cam.. Lifters-pushrods-rocker arms are all comp cam.. Springs-retainers-Locks are in AFR's Heads.. AFR suggest me to modify the spring to high pressure spring for hydrolic roller camshaft..
--AFR's retainers are 1.450" O.D. ,but Comp Cams titanium retainers are 1.430" O.D. will be a problem if I get the comp cams' retainers because of the size differences???
