Mopar spring seat machining?

Hey guys,

So what's the consensus for using Mopar Springs on a 7120 head, should I cut the spring seats down or run the stock height on the seats. It looks like at installed height I'm around 130 with new springs but I'm guessing that will be down to about 110 after 3k

Opinions?

You are correct. At 1.64" they will be around 113 when broken in. I had mine cut to 110 lbs seat load. Its up to you and what cam you run.

Xj,

Is that 110 at assembly or 110 broken in? How much did you have to machine the seat down?


Thanks
Dean
