Description

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. 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

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.

Comfort& Quality
Size: 20" Neck 35"-36" Sleeve, Color: White
Excellent shirt. Ordered for a Risky Business bar crawl and the fabric was so much nicer than the other two options I ordered. It is packaged so nice with pins and feels luxurious (great if you’re giving it as a gift.) It comes wrinkled from being folded in the packaging, but i steamed it and then it did not wrinkle while driving or sitting throughout the night. It’s nice and light. Only downfall is there is no pleat in the back.

Nice shirt.
Size: 17.5" Neck 35"-36" Sleeve, Color: White
It fit perfectly and looked very nice. However, it was much thinner than I thought. And when you wash it, get ready to iron it. This is not a permanent press shirt. It is not wrinkle resistant. I would not buy it again.

Casual Crew Neck Summer Shirt
Color: Denim Blue, Size: XX-Large
Ordered the dark blue. It fits great and looks wonderful on. Very comfortable! Good value, and feels well made. The fabric is just right – not too thin, or thick. I wore it with a navy blazer and beige pants to an outdoor event (shade and sun) and was totally comfortable.
