Default piston/deck clearance: how much is too much?

so, im wondering, would i be able to get away with .030" above deck? when i had my n/a block done, i ended up with a total of .024" above deck, i believe stock is .020?

i could always get a 2.0mm mhg to avoid piston to valve contact, im just worried about top ring and ringland.

if anyones got an opinion about this, lemme know, itll help with the easy stroker setup.

I dont believe you'll have any problems, just use a thicker headgasket.

aight. this is for the stroker, they are basically gonna be custom 1.181" compression height pistons for a b-series honda with machined wrist pin sizes. decided the 1.52:1 rod/stroke ratio was too little, so these will allow keeping the stock rods. any more info if anyone wants to pipe in?

yea i know, but they are the ones with the right compression height, and since they are forged and would be modified. sooooo...i say they are serving the higher toyota purpose.
