If you have a slightly taller block or have decked the heads, the distance between the distributor mounting pad and the cam gear/oil pump drive may be different. MSD offers these Distributor with an adjustable slip collar with 1.5" of adjustment so you can be sure the distributor is installed correctly. The distributor shares the same features of the standard Pro-Billet Chevrolet model including a ball bearing guide, long sintered lower bushing and an oil seal. To trigger the MSD Ignition a maintenance-free magnetic pick-up is secured in the billet base of the distributor. Just above this pick-up assembly is an adjustable mechanical advance assembly.

Brightens, doesn't firm
Color: Cyano Pink Spicule
I've been using this for about a month now, every night on my face and neck, hoping to reduce the appearance of wrinkles and tighten some of my skin in that area that seems to be losing elasticity. On my neck, I've honestly noticed no real difference in 4 weeks of continued, consistent daily use. The skin on my face does seem brighter and somewhat less textured than before, but I haven't noticed any change in the issues I was hoping this would resolve, based on the claims and how it was marketed. So... not a bad addition to my skincare, but not the solution I was looking for.
Some have expressed concerns about it tingling or stinging... You can feel something when you apply it, it's almost like the feeling of static electricity, but it's very mild. I wouldn't let that stop you from giving it a try if you were concerned about it. It didn't cause my sensitive skin any breakouts or redness (although I was applying it at night before bed, so perhaps any redness was calmed overnight). I'm going to go ahead and finish the bottle, but based on these results, I probably won't repurchase.

Really enjoying this product - Big confidence boost
Size: 2.02 Fl Oz (Pack of 1)
I was a little skeptical at first.. I saw a different brand of cyperusrotundus oil circulating on tik tok and was super interested in a natural remedy to treat facial hair. I did some digging and tested this one. I’ve been using it for about a month and I have to say I notice such a big difference in the texture of the skin on my face. I’ve seen some significant improvement in facial hair growth overall!! Im hoping with prolonged use, it will make an even bigger impact - but so far I am very pleased! I use it 2x a day and I’ve been feeling more confident! Would definitely suggest trying this!

Does work
Size: 2.02 Fl Oz (Pack of 1)
I've been using this oil for 3 weeks on my face and do see a difference in hair growth. I am an older female and it seems to slow the growth on my face especially on my chin and upper lip. I mix a couple of drops with my moisturizer in the morning and use it alone at night. It does make my face feel soft and rubs in nicely and not greasy.
