    Headwork begins......

    The castings are pretty good as far as core shift, but some alignment, and casting correction is needed, as well as cleaning up the short radius





    Intakes nearly finished on this head.......





    Exhaust side still undecided....?????

    As you can see, the exhaust side exhaust valve could be larger(original is 34mm).... the seat is even large enough to accommodate a bigger valve.*





    A bigger valve is EASILY available, the Toyota 2/3TC engines use a nearly identical exhaust valve(length, stem, keeper groove) except the diameter is 36mm!






    And if you look back to the castings, the exhaust port appears to be able to support a larger valve.....





    So... that pretty much leads me to where I am right now...**Getting the flowbench prepared to run the hemi heads.*





    The thought is to test the current valve and see if we are above/below a flow ratio of 65% of the intake flow is the exhaust flow.* Above 65%, leave it alone, run a 34mm valve, with a fresh valve job.* Below 65%, and have the valve seat machined to accept the 36mm*valve.



    To run the head, I need another one off tool....* *a "new" valve actuator... a friend will need to weld that nut(plus another) to the metal bar





    more to come........*

    people often ask me why do I post up my work... sometimes its so others can see what I've missed.






    There is something in this I missed...... Note the invoice shows 2 head gaskets... not one left, and one right????


    A reader "from another forum" noticed it! Why can't I have the same gasket.... because the cooling from one head to the other would be significantly different!!!






    Catching this now saves me time... money... and anger issues later.


    More to come.....
