Hey guys i just installed some 1.6 com pro mag on the car with new spring and a freind of mine told me there rockers should make any noise since that are a full roller. well my rockers do make a little more noise than the stock 1.5s is it saposed to be this way or is my frined right. I adjusted the valves with the motor running and tighten them down a 1/4 of a turn then set the poly lock and im sure non of them are lossed i checked three times.

Pro Mags have been known to have a little noise.

Yep my Pro-Mags are pretty noisy.

Not real noisy, but a little bit more than stock. I've used the pro mags and I could hear a little noise with the hood up, but with the hood down, couldn't hear anything.

Roller rockers are noisier than stamped. That is why the LT4 Vette with it's stock roller rockers got composite valve covers, to dampen the extra noise.

If properly adjusted, they should only be a little noisier than stock, now if you hear tapping on the valve covers or clanking, that's a different story.

Thanks for all of the help guys i think i am going to readjust the valves with the motor off this time instead of on just to make sure that every thing is right

Actually dialing the adjustment with the motor running is more accurate and consistent.

yep my promags drove me nutts I thought they were loose but adjusted twice and it is what it is. Also got a LT4 knock module 2 days after installing the promags and it made my car feel like a new car.

...as a matter of opinion...

Engine on or off works just fine. It's more of a personal preference.
