Finally got my ramcat broadheads grouping with my field points after buying a new sight and whisker biscuit rest. I had to lower my rest a good bit to get them to hit together and now if you look at the bow from the side the nock point is higher than where the arrow sits in the rest; however, my arrows still seem to be flying good. Anyone else experience this with a biscuit?

I ain't a fan of a whisker biscuit personally but to each is own.
I would check cam timing or need to play with the timing to get to shoot level.
What are you calling nock high 1/8 inch or 1 inch? Some bows will tune a touch nock high or you could have some vertical nock travel issues that needs tuned out.
What bow and what's the specs?

1/4 inch nock high.

1/4 is a tad much I'd give Larry Odell a call in Sardis and run it up there he will get you straightened out. Bet you got a lil timing issue goin on.
Are the specs you listed actual or what it's suppose to be?

They are the actual specs.
