Description

They feature deep valve reliefs to accommodate high lift camshafts and larger valve reliefs for +1mm valve sizes. The custom skirt design and accumulator grooves contribute to their performance.

Key specifications include an 82.00mm bore, a +1.0mm over size, and a 12.0:1 compression ratio with a 5.5cc dome. The package includes wrist pins, double pin oilers, and pin lock grooves.
