COMP Cams Valve LocksEb Mach Stl 7Deg S - Set of 100Most people believe that the tang inside a valve lock holds the retainer and valve spring in place while the engine is running, but this isn't the case. The cross section of material in the tang is not strong enough to withstand open spring loads of 1000 lbs. or more. The sole purpose of the tang is to temporarily locate the lock, retainer and spring relative to the valve until the taper of the retainer can nest around the outside surface of the lock.
Most people believe that the tang inside a valve lock holds the retainer and valve spring in place while the engine is running, but this isn't the case. The cross-section of material in the tang is not strong enough to withstand open spring loads of 1000 lbs. or more. The sole purpose of the tang is to temporarily locate the lock, retainer and spring relative to the valve until the taper of the retainer can nest around the outside surface of the lock. This creates a collet effect that binds the two together. The more spring force exerted on the retainer (as the valve opens), the more force applied by the collet effect to keep the retainer and lock in place. With the emergence of valve sizes other than the standard 5/16", 11/32" and 3/8", it is important to make sure the valve locks match the valve size. There should always be a small gap between the two halves of the lock when they are properly positioned on the valve stem. If the two halves fit together without a gap, they are too large. If the locks fit tight to the stem and leave a gap between the middle of the lock and the O.D. of the stem, the locks are too small. Our line of stock replacement 7 valve locks for stock engine rebuilds are recommended only for street applications with lighter valve spring loads and are stamped and hardened for superior wear resistance. Also available are machined 7 locks and titanium Super 7 Locks for some applications. They offer the same valve spring location accuracy as our Super Locks without the need to change to 10 degree retainers.Shipping Notes

Nice
I love it. It's a nice slim wallet. Nothing special, but looks really nice, works well. I've been using it for a month with no problems. It's nicely lined, seemingly well made, etc. I got a good price on it, so I'm happy.

Cards don’t fit tight
Color: Black Embossed
My credit cards fall out. Needed a more secure alternative— still stayed with Tumi though.

Wonderfully made, but not well sized for US currency
This is a very nice slim billfold, but unfortunately, it's not well sized for US currency. Probably for Euros. US Dollars fit, but it's a touch too narrow across to easily insert a bill. So you'll have to very diligently straighten and align a greenback to make it fit.

Class and elegance
Color: Gold
I absolutely love this watch! My grandson also loved mine so I bought him one for Christmas. This is the 4th Citizen watch I have purchased. 2 are ecodrive and 2 are battery powered. I have to say I do like the battery powered watches better for their weight, lots lighter on your wrist than the ecodrive I regularly used to wear. This watch has taken a beating, as it seems like I'm always hitting the face on something, and has performed beautifully. I figured that I would've replaced the crystal by now but I haven't had to. My grandson admired and wanted mine, (I can't part with it because it has special meaning) so I bought him the identical model. I have worn mine in water, extreme cold, and out to dinner. It looks and performs beautifully. This watch is classy, elegant and beautiful and it's not a giant timepiece although you may have to take it to your local jeweler for band sizing. There's videos on u tube but I don't recommend trying that for taking links out. I say beautiful because as a woman wearing this watch it's not overwhelming and screaming look at me I'm wearing a man's watch. However this watch is handsome looking on men, my husband and grandson lol. The band is smooth, doesn't kink or pinch my wrist and when fitted properly it doesn't end up face down or sliding over and staying over on the outside of my wrist. Only drawback for me is I'm not used to the day dial and sometimes when setting the time bc some months are shorter I tend to be a day ahead, easy fix. I've gotten lots of compliments on this watch and would definitely buy it again
