H defiantly stands for High compression but whats the numbers mean?????
Was told about a bit of a theory with them numbers but its not working out.
Dose anyone know or wants to guess,because thats all I'm doing.

Hi Dane
I reckon the number next to the H is a pattern identification number.
Each pattern for making the sand casting mould would have a different number for quality control.
That's my theory anyway.
Cheers
Dave.

Hi KockumThis is what I was told years ago .[It may be a pile of crap .]
All the 20F3 heads were sent straight from the foundry to Dave Bennett for special machining and final completion .
They were flat out getting these heads done in the time frame that Holden specified
Holden wanted to send more heads to be done - I can only assume these were the 27F3 ones .
Bennett said they could not take anymore heads and finish them on time , so Holden was forced to do the special machining and final completion themselves .
I have opened a can of worms so go easy on me MIKE 73 [LOL]
Thanks
Thanks Bazza,has anyone got anymore in 73 casting.C223,20f3,27f3????
