Why It Matters
The GTV-2 casting has beefed-up intake and exhaust ports, 20% larger than stock, with added material around the combustion chamber for deep fly cutting, so it allows massive porting without welding. Machined for 94mm, it is a direct fit for big-displacement stroker builds.
Installation Notes
- Lash caps (P/N 00-4006-0) are required for all stainless steel valve applications — sold separately.
- 12mm long-reach spark plugs must be used in place of stock Bosch plugs.
