Default afr spring question

has anyone ever heard of the dual coil springs on the AFR mongoose heads (the ones good to .600" lift) setting off the factory knock sensors? i know that this can happen with some after market springs and i was just wondering...also, do you think these springs will be okay in a high"ish" rpm engine (7000rpm redline), i'd like to check their site but its under construction or whatever.

The standard 8017 spring from AFR is the same as the Patriot Gold, PRC duals, and Manley duals. It is good from cams in the low .600"s and will easily rev to 7000 rpm with proper pushrod length and lightweight rocker (like the stock rockers).

It is not known for setting off knock sensors.

Would need to know what cam you're running, how much your heads have been milled, how thick your head gasket is, what lifters your'e running and what rockers you're running.
