what heads to run on a 273

I havent messed with the lil 273, though it's a small bore 318/340..it's too small for my interest/$$$$

Just mic across the valves if you have the heads...and there will be ur answer.

the magnum stuff cc'd around 153.
stock la 360 1.88 valve heads cc'd around 160, with the 2.02 at 155cc.....the bigger 2.02 factory tulip valve eats up a lot of bowl volume...'so much for the too much intake port bs'...lol...and thats the only explanation i have for the funny diff between them, both were bone stock 915 castings, stock valves. fwiw

If you 'read' aound mopars press releases...u get impression there are 2 iff mag heads, though some say they are ''1 size fits all''....

Something to read, and it coincides with my findings on them

now if you check my ''360 head trip'' thread...

you can see the actual flow numbers of the 1.88 974' casting head....and then even some ported numbers. They are about as good magnum stuff, performance valve job on them both would make them nearly identical....and i think the diff is mainly from the 'skinny valve stem'....and remember....the PORT controls velocity, not the valve.
