Anyones h/g thickness affect their timing considerably?

[SxMachine]

Reassembling my head and making final decions on parts. My pistons are 86.5, 8.5:1 mahles. My deck is fine after being checked for clearences. Considering a 1.5mm cosworth but wondering if the thickness would affect my timing at all. Im not quite ready for cams/gears at the moment.

I have an Apexi 1.5mm on my car and it did not effect cam timing on my motor.

Nothing in my motor is stock
But the head was decked with no real material taken off (don't have machine shop receipt in front of me, but the head was straight in the first place).

Yea I read your post before I bought my block to the machine shop and even brought the issue up to them sooo...i dont kno lol. My block is still sitting wrapped in plastic. I did call the machine shop again recently though and i'll be bringing my block back up there to check again, after finding out mahle's piston design hasnt changed.
