Right now I have AFR 8019 springs on my 195 AFR non competition heads. I have the 8117 springs sitting here but I'm still wondering if it's even worth while to do. Steve40th said he had this issue a while back and changing springs to a lower rate helped with overall feel on the engine. But that was his engine and I'm sure mine is different than his was. I'm not doubting Steve I would just like to hear some other opinions on whether it is even worth while to do.
I'm still having split blms of 20% on average higher on bank 2 than bank 1. I've checked everything I can find to check and cannot seem to help them any. Could these springs be contributing to this spilt blm issue? Cam 226/230.565.565 111 lsa AFR 195 street eliminators(non comp),58cc chamber, .026 head gasket Stock bottom end A4 w/2800 stall 3.45 dana 44 weight 3400 lbs with me in it Here are the spring specs: AFR-8019 1.270 OD seat pressure 155# @1.810 Premium Grade coil bind 1.080 Rate 428 Max recommended lift .650 AFR-8017 1.290 OD Seat Pressure 135# @ 1.800 Premium Grade coil bind 1.050 rate 360 Max recommended lift .600 |

I'm running a similar spring to your current, without any ill effects. Before these I was running 918 beehives and they didn't work well with my camshaft (224/230 605/622).
I don't see how your current springs could effect your blms? |

Steve, the beehives I was running was an early version that was rated at .625 max lift.

One thing that bothers me about these big ass springs is my lifter preload doesn't seem to want to hold. I set it at 1/2 turn a couple of times now and after I run the car a while those rockers are sounding like a sewing machine just clicking away. Maybe that is normal I don't really know. There's a couple of them that are noticeably louder than the rest.

You had the good ones like me, very early before they were made in a foreign country, at least COMP Cams. I will buy from PAC racing if I need new ones. |

Could it be to stiff a spring for the lower lift cam?
