RE: That's why Ford revised the 4v heads (smaller valves), in '73. [n/m]

same reason why ford dropped the the 69 boss 302 size of 2.25 to 70 boss size 0f 2.19,and some racers were filling the ports with some epoxie stuff for better tourque values,and this is why the 351/400 m head is hot,plus the later ones had hardend seats,saved a lot of dollars in machine work,and the 2v ports were sufficient,for street and racing use,but i always wondered about the truck applications,ps,with that open chamber head,you can bump up the timing,with good fuel and no spark rattle,oh yes they done make special gaskets to put m heads on windsor blocks.only drill a few holes
This thread, so far...
