The "USA" head in the picture is a well massaged 74 RACE head with Ford 300 1.78/1.50 Valves. So I just wanted the comparision of a RACE head I have and the Heart Chamber head.

Man I wish I knew if you guys were serious about sending it to downunder Mark to have copies made up. Is that Mark form Aussiespeed??? Being downunder myself, I'll save the $2,500 PPR wants for a stage 3 head and wait for these to be cast up. I'd even lay down a deposit and order now. |

Sorry JohnIs that Mark form Aussiespeed??? Being downunder myself, I'll save the $2,500 PPR wants for a stage 3 head and wait for these to be cast up. I'd even lay down a deposit and order now. I really dont think it will happen. At least not any time soon. Mark work in Aluminum anyway. Frank |

Hi Frank and congratulations on your head buy!!! Martin is a friend of mine also and he told me about shipping this head to you. Glad you received it!!!! It will be very good if you guys can put this head in a flowbench and run back-to-back numbers with other heads!!! That would be great! If you post more pictures of all the markings in the head casting I can tell you if this head was cast with this chambers or not or give any additional info on it. Just for the records, in performance terms it makes no difference if the combustion chambers were cast in or welded and machined. Regards! |

USAJon if you look at one of the pics you will spot the casting date saying "19-9-77" or "9-9-77" DD-MM-YY ... so this head was cast on September 1977. Regards!

.........it might be different from your head. There are three visually different north American heads. |

As far as I was able to check pictures from USA production heads I can say that the Argentinean castings are the same as your first Slant Six heads, the ones with spark plug tubes and with the first combustion chambers, not the ones with the "smile" as I read somewhere. I do have a USA head out of a 79 Dodge Van, with the revised Combustion chamber, the provision for an air valve at the rear and without the plug tubes. Comparing this head to ours, the ports are much smaller than our production head ones, is like the intake ports on the USA head are almost the same size as the exhaust ports on the ARG head!!! But remember I'm NOT talking about this head here, but the regular production heads in my country. |

So are they planning on remaking this head. Or anyone on here have the intention of doing so? |

Anyone planning to actually do a head like this will need something like $20-30k or more to get started. Unless we can put that kind of $$$ together, there is no point in discussing such a project. Lou |

I'm going to agree with that. Plus, that's a iron head and already machined. The best it would be for is a couple of rudimentary measurements. You're looking at a minimum of four cores and in order to be cost effective you'd have to do it sand cast. So actually more like five cores, (valve side exterior, spring side exterior, left and right intake exhaust cores, and water jacket core). Plus for ease of workability you'd really want to do it in aluminum, so you'd be better off starting from scratch because the two mediums are really different, i.e., expansion characteristics, etc, etc. It's nice to dream, no? How come nobody has a line on importing these yet? |

We still need $30k plus someone to make patterns and all... That head Frank has was only sparsely made 20 yrs ago. Lou |

Or a set of measuring tools, AutoCAD, some type of solid modeler, and the ability to sneak into an aluminium foundry. Just saying. Plus a butt load of patience. |
