COMP Cams Valve Locks 3/8in Four Groovelock angle and 3 8" valve stem size are a perfect replacement lock for stock engine rebuilds. They are recommended only for street Applications with lighter valve spring loads. It is critically important to make sure valve locks match the valve size.

lock angle and 3/8" valve stem size are a perfect replacement lock for stock engine rebuilds. They are recommended only for street Applications with lighter valve spring loads. It is critically important to make sure 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 OD of the stem, the locks are too small. Most people believe that the tang inside a valve lock Oldsmobile the retainer and valve spring in place while the engine is running. This is not 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.This Part Fits:

Soft
Fit Type: Regular Fit, Color: Navy/Dark Blue, Size: X-Large
They feel nice, but shrunk a little in the wash. The fit before shrinking was perfect, afterwards it was just slightly too tight. The length before and after was too short for my preference. I do have a slightly longer torso though. If you are normal height then they will likely work great for you.
The material is super soft and comfortable.

So soft and attractive
Fit Type: Regular Fit, Color: Heather Grey/Heather Grey, Size: X-Large
Bought these for my husband. He loves the fit and they're so soft and don't wrinkle easily. They're also a nice weight. I've washed them a few times and they don't pill or shrink. Wish they came in a larger variety of colors, but plan on ordering more.

Shockingly great affordable basic T- Shirts
Fit Type: Regular Fit, Color: Black/Black, Size: 6X-Large Big Tall
I love these shirts! The fact they are big and tall is amazing. Better than Hanes, Fruit of the Loom, and Gildan. I am 6 foot 5 and heavier than I'd like to admit. I also have a wide chest 64 inches(Its hereditary). I need width and length! It is tough to find a shirt that is big and tall. Literally it's one or the other. Amazon of all places solved this. I did get two that weren't right they replaced them swiftly. Also for some strange reason white is a tad bit smaller in the same size. Usually it's the other way around with other manufacturers. I could not find black shirts that fit me comfortably for years! I was convinced it would be impossible to ever find any that would fit. This felt like a long shot and it paid off! Which is rare. I do not dry them in the dryer I know they will shrink(Probably wouldn't hurt to wash cold). If you want to dry them and you can I would go size up. Not too thin or too heavy wouldn't consider it an undershirt.

New default shirt
Fit Type: Regular Fit, Color: Navy/Navy, Size: Small
Amazon has again proved that it did good research about what makes a good basic garment. I've been wearing these for a few weeks now and honestly I forgot about them because they just fit and are not annoying and don't look bad. They are good. Also the cotton seems high quality and is soft. Also the small fit as expected.
