OK... I know this has been discussed many, many times.

Tried using search, but it doesn't like me. Each time I either get error msgs., or the screen just rolls back to the inquiry screen, or it just gives me 1 page of results (while indicating many more) and when I select pg.#2, it just rolls back to the inquiry page.

So, search is out. Forgive me in advance for asking about what is surely an oft asked and discussed question.

Have access to a tii head (free). Is this a good upgrade to my stock M10 motor? Have a 32/36, Crane and tii manifold (only mods).

Not certain, but believe all '76s (mine is Auto) came with a 121 head?

Do I need a piston swap for this? Does it use stock valves? What else would I need to convert to use this head? Is it worth it in the end?

Any help is much appreciated.

Cheers!

In my opinion, not worth it. Tii and standard head use the same valves and cam. So you would be better off upgrading your existing head.

76's came with e12 or late one with e21 2.0 head and mostly flat tops pistons.

There is nothing particular to a Tii head, if its just the fuel pump rod hole that is not drilled.

fwiw, a Tii sourced part doesnt mean automaticaly an upgrade or a performance item. It isnt made of gold.

If you realy want to upgrade your stock 76' motor, assuming its original (flat tops) get a 121 head, you will get a litle bit more compression ratio than with a E12 or E21 2.0.

Yeah but free is good anyway.

...... and any "FREE" head is suspect

-Tiny cracking you bearly see?

-Warped beyond machining tolerances

stay with, and have your present head tested, resurfaced

with the upper timing cover screwed on,

valve springs replaced, reface the valves and seats,

measure valve-to-guide wobble tolerance, replace guides

if needed, replace valve seals.

maybe the "free" head is ok after all the above repairs - then sell it to pay for your orig. head reman -

or keep it for a 'spare' for your car in 20 years when you'll need one
