Are the ex valves in a slant rotating or non-rotating. I was looking at some spring options and this was a question Edelbrock asked. |

The only Slants I know of with rotators was some of the exhaust valves on industrial engines. The automotive Slants did not. |

Keep valve spring pressures light unless you are spinning some high RPMs. Most people use to much spring pressure in a SL6, especially for "street/strip" engines. DD |

When you say light can you give me some numbers I changed cams to a P4286678 and the spring is Edelbrock performer pt # 5877. Ishould be able to use my stock retainers with this spring also. |

On a street SL6 that stays under 5,000 RPM I target 90 lbs on the seat and 200-220 lbs at full lift DD |
