Some people have reported issues with hydraulic lifters with a larger cam profile, even if the poncam is quite mild. Did you happen to fit an oil restrictor in the block during your build? That is a potential issue if you're retaining hydraulic lifters. Alternatively it's possible that your lifters are in need of replacement. I'd definitely try an additive first to see if that gets rid of the problem. It's not a solution but may buy you some time and can help confirm the lifter is your issue. In the 4G63 we found the Proma MBL8 additive to be almost like magic - pour it in and within 30 seconds the engine would be silent.
