flat top pistons okay? 3.0 181 rebuild

[John2037]

Hey guys, the OEM pistons are dished and the master kit I just recieved came with flat pistons. I have always just replaced engine parts with the same parts, never really got into raising compression for HP or whatever.... Other than some timing/fuel adjustments -what are your thoughts on flat pistons replacing the OEM domes. Nothing to worry about or ship them back?

.20 overbore pistons

Unless you understand engines in great detail...That is messing around with compresion ratios replace the piston's with what was in there or confirm with a engine builder your not upping your compression ratio...By the way use orignal gasket along with that for the same reasons.
