Description
ROUND/OVAL PORT COMPATIBILITY: Designed as a premium aftermarket replacement, perfectly fits Small Block Chevy (SBC) V8 engines requiring a round or oval port seal. Ideal for specific aftermarket cylinder heads to ensure flawless fitment and optimal exhaust flow
HEAVY-DUTY COPPER: Don't settle for flimsy, multi-layer gaskets that bend easily and fail after one use. Cikroci gaskets are precision-cut from thick, solid copper. They will not blow out, shrink, or deteriorate, providing a permanent seal even on slightly warped or pitted flanges
PRECISION 1.18" EXTENDED BOLTS: Our premium socket head cap screws feature a true 1.18" (30mm) Under Head Length (Thread Length) and a 1.50" (38mm) Overall Length. This extended design is optimized to provide maximum thread engagement for modern aftermarket headers with thicker flanges (up to 1/2" thick)
HARDWARE CLEARANCE ADVISORY: The kit includes 12 flat washers to prevent interference with tight header tubes. Important Note: If you are running older factory iron heads with blind threaded holes (common on some 327 blocks) paired with very thin-flange headers, these extended bolts may bottom out; shorter bolts or extra washers may be required
COMPLETE INSTALLATION KIT: Reusable and cost-effective. The package comes ready for a hassle-free upgrade. Includes 2 x Copper Exhaust Gaskets (Round/Oval Port), 12 x 3/8"-16 Premium Allen Bolts, and 12 x Washers. Provides maximum clamping force and a custom look for your engine bay
Eliminate Exhaust Leaks Permanently with Cikroci Round/Oval Port Copper Kit
If you are running aftermarket cylinder heads or custom headers on your Small Block Chevy that require a round or oval port profile, standard square gaskets won't cut it. The Cikroci Solid Copper Exhaust Gaskets provide the precise fitment and extreme durability your V8 demands. The exceptional malleability of solid copper acts like a custom-molded seal, creating an impenetrable barrier against exhaust leaks.
Honest Specs for Professional Builders
Our kit includes 1.18" (30mm) thread length bolts. This extended length is purposely chosen to safely secure modern, heavy-duty aftermarket headers with thick flanges (up to 1/2"). Please measure your flange thickness and check for blind holes (especially on classic factory iron heads) before installation to ensure perfect fitment.
Package Includes:
2 x Copper Exhaust Header Gaskets (Round/Oval Port)
12 x 3/8"-16 Socket Head Bolts (1.18" Thread Length)
12 x Flat Washers
Stop wasting time replacing cheap gaskets. Invest in Cikroci for reliable, reusable performance!

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $1 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Cikroci products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
