    Hey all,

    In lead up to a new car project I'll be looking into development of the 250 cylinder head.
    Information I will be looking to gather is as follows.

    - Cylinder pot / water jacket wall thickness
    - Inlet porting for increased flow
    - Exhaust porting for increased flow
    - Port flow and continuity
    - Cylinder pot improvements, continuity and flow

    I will be looking for a scrap head, which will be used for destructive tests to gauge internal dimensions so please get in touch if you have one for the scrap bin.
    I would also be happy to run the same tests for the 225 Head and run comparisons.

    May also be looking for a 250 head in usable condition to build for the car project, again please get in touch.

    Any interest or questions always welcome!
     
  2. Might be worth considering using clio 197 head instead. Easier to find, large ports, 250 inlet fits.

    Absolutely, I would also consider a 197 head in place of a 250.
