Unlock the full potential of your Engine build with our upgraded head stud options. If you're building an engine for high horsepower, these head studs are essential for higher power levels.

When you're talking head studs, you're ultimately trying to increase clamp load onto your gasket. To get more clamp load, you need stronger material, or bigger studs.

Stage 1 engine builds should go with the 10mm CA625+ head studs. These studs are proven reliable to 800whp with a stock or Cometic MLX head gasket. This option is as big as anyone with a non-sleeved block needs. This option even works well for Stage 2 engines that are not using sleeved blocks.

If you're going sleeved engine and are going to put it to work, your best bet is to step up in stud size. Our 8740 Chrome-Moly 12mm head studs are perfect in-between step. These studs are a very affordable option that is good for over 900WHP. They're the same thread size/pitch as the 12mm CA625+ head studs, so you can always step up later when you refresh your engine. BLOCK MACHINING AND HEAD CLEARANCING ARE REQUIRED, ALONG WITH A SUITABLE 12MM HEAD GASKET.

If the sky is the limit for your build, it's time for our 12mm CA625+ head stud option. There is no bigger head stud available for the platform. These studs are good for over 1200WHP. Do it once, do it right. BLOCK MACHINING AND HEAD CLEARANCING ARE REQUIRED, ALONG WITH A SUITABLE 12MM HEAD GASKET.

All stud sets come with washers, nuts, and instructions.

Engine fitment for 4 cylinder Mazdaspeed DISI and Mazda MZR engines, and Ford Duratec and Ecoboost engines.

THIS STUFF WORKS
I’ve been bed ridden w some type of facial/sinus infection for months on and off, and when I tell you this was the ONLY thing that helped w my intense headache pain, IT REALLY WORKED ! Best thing I’ve ever used tbh, and I’m always trying natural things for pain relief. (I hate pills but sometimes nothing else works for my chronic migraines) but this stuff is amazing. and it smells so good ! I’d totally buy again, and I’ve always recommended it to two other ppl, and they loved how it worked as well !

Not a nasal spray put in temples
This is NOT a typical Nose Spray. I did a search for nose spray. I read the description. I read the reviews. It arrived quickly. I sprayed into my nose. For 10 minutes this stronger than vicks Nasal Spray burned my sinus, throat and eyes. But no congestion the rest of the day. Bought some for a friend. Good thing he read the box. PUT on temples.

No more sniffles
I used the spray today. Usually I blow my now all day and night 24/7. But today it’s been 3 hours and I haven’t needed to blow except for 2 times and then it was practically nothing. I recommend this product to everyone.
