Your experience with 232 head on 308 ?
  Seems the factory used them on 7X engine,so best performance I assume.I have a good H145 aluminum head as well,would that flow better perhaps ?Chuck Vorse told me he is running aluminum on all his Hornets,so that's a good endorsement for aluminum. 
 Thanks for ur comments...

    Looks like we will make a run of the new aluminum heads this fall if you are interested in one of those.  Better flow and better overall design.

    $1,250 - as of Jan. Expect up a slight bit but in the same ballpark.

    In my own experience, with 7x intake valves and a pretty big block relief, a 232 head was fine with 91 octane pump gas for about 6-8 months. Once there was come carbon buildup in the combustion chambers, it started to ping, and I had to back off the timing a little bit. I ended up going with a 262 head for this street car.

    232 head on a modified 308 will detonate (ping) regardless of octane unless the head has the sharp eyebrows removed. Rudy Bennet, an older long drag racer has pictures of stock 232 compared with the factory 7x 232. Rudy is getting up there but would still be the resource on that....

    Rudy Bennet and Chuck Fellows designed the new aluminum head, so all the 232 head info was considered.

    Rudy, Its really great to see that you're still overseeing the Forum and I'm glad that Ken saved your 7x research for others .....

    All of Rudy's experience has gone into the new Twin Vortex head and it takes it about as far as the flathead design will allow!  So a big thanks to Rudy from all the Hudson Hi Po folks.
