Max. Valve Lift With Flat Top Pistons

[Uncustom]

Hey guys, I'm currently in the process of building an RB26/30. Bottom end is complete and has Arias flat top pistons with no valve reliefs. With RBs being interference motors, does anyone know what kind of cam lift I should be running so that I don't end up with bent valves? I will be checking the clearances but I'd like to know what to expect. It is a street car so I'm not planning on stupidly high lifts or duration, especially being an RB30. I was considering 10-10.25mm lift, but then considering that the pistons are flat top and without having measured clearances yet, I've decided even 9.15 or 9.7mm lift may suffice for the application.

I would appreciate any help,

Cheers

I've got the cp dome top pistons in mine with 10.5mm of lift and have plenty of clearance
