NEED HELP!!!! I think hughes engines sent me 1.5 rockers instead of 1.6 ratio...ughhh

I have 1.6 Hughes rockers and my roller cam is 360 lobe lift. I'm only getting
.540 lift at the exhaust valve on their 3644 roller cam which is where the cam spec is for a 1.5 ratio rocker. I checked the lobe lift and it's right on the money @ .360 so I know the cam is correct as listed. Did the whole setup with their solid adjustable lifter and pushrod too. Got the geometry perfect and I was dissapointed to see how much lift was lost due to the poor lifter/pushrod angle. I've been told that the roller lifters being so much taller in a LA block makes it even worse as far as loss of lift goes. Having seen where I ended up on lift, I would have to agree!
