Description
Simulates the bore distortion of a torqued cylinder head during the honing, boring, and ring gapping process. Proven to reduce blowby, reduce oil consumption, and increase reliability. Essential for high performance engine builds. Top bore edge radius makes it comfortable for ring gapping. Included spacers duplicate cylinder head deck height to accurately reproduce block stresses. Use with aftermarket head studs or OEM head bolts. CNC machined from tempered and anodized aerospace grade aluminium.
