afr 345 big block heads

I can buy a set of 345 afr's for $1200 and wondering if these would be to big for my 431? My iron heads are 320 with alot of port work etc.etc. I need to let him know before tomorrow or he's going to post them up for sale...He says that they only have 40 passes on them and i can hear them run on his car before he pulls them...
