1970 340 with x heads

yeah....i have a 340 with those cut down trw pistons in it....has not run 15 yrs...still a standard bore...
my 340 TA motor has the TRW flattops in ...just reassembled it last weekend and the heads are not on it yet...so those are fresh in my mind...

i answered that post with my phone and i could not see the other post....
