340 cam timing, 1.6 rockers?

I have valve a lot clearance with this combo;

360 cid
Zero deck Hyper-U Speed Pro slugs w/2 valve reliefs.
(Super similar as the KB-107’s)
Trick flow heads w/1.6 rocker
Comp Hyd. Roller @ 224/230@050
1.5 lift .538 - .534
1.6 lift .573 - .569

After using clay to see what I had for clearance, I was surprised. Much room left over.

However, I will say a lot about clearance is also the cams timing. More so than the actual valve lift itself. Always check even after you degree the cam in.
