Valve Clearance Spec & Seals

Hi, I'm finishing my Civic Si K20Z3 with : Go-Power KSi Cams & Valvetrain Upgrade.

The question is what are the values of valve clearance for these cams?

Another question, is good or keep the original sparkplugs or i need to put one point more cold sparks plugs?

Thanks!

The valve adjustment would be .007" intake and .008" exhaust cold. For slightly more torque you can adjust the exhaust at .010" The factory spark plugs are fine.

I found the service manual for Civic Si 06 + and the values are slightly different.

Intake: 0.009 - 0.23mm
Exhaust: 0.010 - 0.27mm



The values are different when running cams?
Jeff what are the values in mm for comparison?

Diego,

I thought you asked this question via PM a while back, or was it Marcin? I forget there's so many people getting KSi's now .

I'm using this on my setup:

.008 = 0.2032 millimeters
.010 = 0.254 millimeters

Any other advice before install the cams? I want to be sure of everything, especially the valve clearance spec.

Thanks!

I add another question.
I received my order, retainers, dual valve springs and 16 Exhaust Valve Seals in blue color. But not received the intake valve seals, exhaust valve seals can be used for the intake? Are they the same?

Thanks

We use the same seals for the intake and exhaust. The exhaust seals are made to take a little more heat and we use those on both.
