Hi all, can anyone tell me what the tops of the standard 351c pistons looked like? Are they flat with small cutouts for valve clearance?

thanks

 

all the 2v ive pulled apart were dished havent pulled any factory 4vs apart

 

I stripped the 4v today and the pistons are definitely flat. Was trying to find the make on them, couldnt see through all the carbon on them. I found a name 'adeinus' was about to look it up until i realised it was 'made in usa' with the end letters missing - then i saw the Ford stamp. I'd post a picture, but i'm away from home and the wireless signal is practically non existant.

 

sounds right to me
