what heads to run on a 273

im really shocked to read what ive just read from some of you...

ALL 273/318 HEADS HAVE THE SAME PORTS
SOME ARE CLOSED CHAMBER LIKE THE EARLY 273 AND LATE 302, AND THE REST ARE OPEN CHAMBER LIKE THE 68-85 318 HEADS.

IF YOU GO FROM CLOSED CHAMBER 273 HEADS TO 302 HEADS, CONGRATULATIONS... YOU'VE JUST WASTED YOU'RE TIME AND MONEY.

A better head than all of those is the '234 casting 1967 318 truck/motor home heads, they do not have the heat cross over port in the exhaust which can hurt flow on one port in each head....though still the same intake port as the rest.

If any of you think im wrong, prove it...im calling you out.

If you want more power but dont want to use 360 heads....have a look at the 318 head porting sticky and just have the heads 'you already own' done up like those.
