Stock 8mm case studs stretch and pull out under the clamping load of a built motor — it's one of the classic air-cooled failures. This is EMPI's 10mm chromoly case stud kit (00-4009-0) in stock length, the upgrade that gives a performance or stroker engine the even, high clamping force it needs to hold a head gasket seal. For dual-port heads.

Features

• High-grade chromoly studs — machined to resist stretch and fatigue where stock studs give up
• 10mm thread — the preferred upgrade over the original 8mm case threads for stronger clamping
• Stock length — the standard-height stud for dual-port heads
• Complete with OE-style hardened washers and hex nuts
• Even clamping force across the case for a reliable head seal on performance builds

Questions & Answers

Will these fit single-port heads? No — this kit is for dual-port heads; single-port uses the 8mm kit.

Do I need to machine my case? The case must be tapped for 10mm; many performance cases already are, and stock 8mm cases can be drilled and tapped up.

Why go to 10mm? 10mm studs give stronger, more even clamping force for performance and stroker builds.

What's included? The chromoly studs plus OE-style hardened washers and hex nuts.

What's the part number? EMPI 00-4009-0 (UPC 707924325195).
