Thank you that helps they do have the 1.80 intake and 158 ex and clearly marked 351.was wondering if there's anything special about these heads or just run of the mill stock heads

Run of the mill.
These heads were put on 289s and 302s back in the day to get the bigger valves. However, you got a bigger combustion chamber and lower compression in the bargain. I think they did make a bit more power as the bigger valves gained you more than you lost in compression.
These days, better heads are available off 5.0 Exploders.
Carefully consider your total cost to make them work vs aftermarket heads or later 5.0 heads. You probably do not have hardened seats in those either.

I forgot to mention these heads came off a 351w 4 barrel.all the parts have correct numbers for the vehicle and year block, intake and exhaust manifold except the heads which don't seem to have much information as other heads of this era have.
