What better way to ensure trouble-free valvetrain operation than to install matched springs with your new BOPORT cam. All stage 1 cam and spring kits are a complete "drop-in" meaning no machine work or additional parts will be required for stock heads and stock valves other than our required HLA's. HLA's are available in cam kit form also in the previous section. The Stage 2 and Stage 3 cam and spring kits include matching retainers and keepers. These cams also require the use of .400" tip or .450" tip length BOPORT  or other aftermarket valves for mechanical clearance and proper spring installed height. Confused? Get out complete top end kit in the previous section and we will send you all the parts you need to install the cam of your choice.
