AydinZ71 Posted February 25, 2021 Share Posted February 25, 2021 Just got My head back from Steve’s Machine Shop in Azusa, CA. Here are some pictures and specs. Looking forward to getting her on and running. - N42 head as a core - exhaust valve and seats fabricated to 35mm to meet OEM L24 diameter (race spec limited ). N42 came with 38mm exhaust valves - chambers debured, ground and polished - valve seats deshrouded and some clearance added to exhaust valve seat. - ports ground to 1” into runner, and port matched to manifold (race spec limited) - deck machined to a volume of 38.5cc - with gasket volume and a piton-deck clearance of -0.35mm, yields a static CR of 10:1. - bee hive springs and custom retainers. - viton valve seals Race cam lift .500 (race spec limited) Specifics in attached photo. excited to get the car put together and break her in.
