ARP 444-1102 4441102 Stainless 300 Hex Header Bolt Kit - Pack of 14: Premium Quality Bolt Set for Enhanced Performance Review

Through trial and error, I found that replacing my stock headers with stainless ones made a huge difference in my automotive performance. These headers are durable and built to last. The installation process was simple and straightforward. The only downside is that they can be a little more expensive than other options on the market. Overall, I highly recommend these for anyone looking to improve their vehicle's exhaust and emission system.

I CANNOT STRESS IT HIGH enough IF YOU INSTALLE MANIFOLDS YOU MUST USE STAINLESS STEEL SCREWS! OTHERWISE YOU'LL NEVER GET STEEL. ARP IS GREAT

These are excellent quality bolts from ARP. They're very compact, but I still had to modify four of them to fit the headers I bought for my 5.2L Magnum V8. It's not ARP's fault and if the heads weren't so small I wouldn't even be able to get them to work. If you are looking for good stainless steel boots for SBM, look no further.
