Yes, I am,
ET 215 with 977 and stock lifters
I was having valve float issues starting around 6,300 and up.
I am changing the lifter to Morels.

Are you having any issue with 977 and stock lifters?

I got alot of negative feedback regarding 977s. I'm glad my ETPs were spec'ed with crane 99893 springs

I just looked at my build sheet for my heads and it said 99893 for the springs as well.. What are they rated for??? Lift wise... I had 977's on a different set of heads and these looked different. They have a red stripe on them.

Back to the other question, I have a set of LS6 heads with 977's on them and wondered if they would work with a G5X3 on stock lifters.
