    These heads are pretty much bullet proof and steel reinforced so I would doubt it would be warped.

    They all require work. Each chamber has differnet CC's. Although there is no reason you cant slap one on, they work much better after machining

    I did not know the Clifford heads were steel reinforced. What reinforcing is used?

    I assume they are using the same molds over the past 20 years. Yes they all need work to be exact, but there is no reason you cant put them on with out the work. There are differences in the size and depth of each chamber.

    BTW clifford offer two sized CC 's one at 58 and one at 72 CC I believed. The lower CC head is no longer made and is sought after more often

    So would this provide better performance (or higher compression, or higher flow)on my 7X prepped 308, or should I just stick with a cast iron 262 head?

    Hi Silverone! I'll let the experts chime in here, but it seems the general consensus is, use aluminum for aesthetics or weight-saving factors, but performance is generally nil compared to what you've done with your 262 head, if I remember right. If your current head is milled .030", you've all ready "got 'er done".

    Curious as to the other responses, though.
  • Question for the experts- how does the clifford head compare with a 232 head as far as compression?
  • You really do not have to compare the cliford head to any of the others. After you get the chambers straighen out and equal (if you want to go to the trouble) you can mill and mill to the desired cc's or compression ratio you want. I'm running 48 cc's on my '41 racecar which equals 12-1 with my set up---yes 12-1. Who says it can't be done.

    Wow!:eek: Randy, does that require racing fuel, or at least a racing fuel/gas mix?
  • Yes it would require racing gas--110 octane, but I am running methanol--one half the price of rac'in gas--may use a little more--motor runs cooler and cleaner. Hope to switch to fuel injection this spring on meth. We'll see what happens.

  • Ken, in theory you may be correct in your assumption you will us twice as much fuel but in practical use we have used both racing fuel and meth and have found we may use one third more fuel. It is still cost effective at $3.50 per gallon compared to over $10.00 for VP products. As far as corrosion, we have not had that issue with my webers or our Barry Grant carb on the Super Gas car. Of course we drain over the winter and fill with reg gas and drain when racing season starts.

    It's still listed for $650. No bids.

    Since the Clifford head is much thicker, how do do you attach and run the Twin H-linkage?
