A new head for a 2l engine

[archigraphe]

I had this head,

a beta 1800 coupé head (with reduce combustion chamber)

a beta 2l ie (with .....I don't know what is particulare....)

a strada 105 TC head  (with 43.5 adm. valve....)

as I want to rebuild one to place on my engine....

And I want to manage the comfort torque from my 2l Engine.

For you, what is the best choice....

Nota: the engine is still standard and has the flat piston for 8.9 CR.
the use is for TSD Rally ( no race, circuit...)
Thank for your answer.

The ie head is the same more or less as 2 litre carb.

1800 head has large ports like 2 litre, will give a very small compression increase,  but will give no advantage really, as the 2 litre has a better combustion chamber shape with less valve shrouding.

The best head is 105TC, but only if the ports are enlarged to take advantage of the 43.5mm inlet valves.

All the heads will benefit from gasflowing and 3 angle valve seats.

Hi,

So I'm going to work with the strada 105TC head to rebuild and prepare it.

I'have a complete head .

 I'm going to checked it, disassembling and prepare cuting with the 3 angle seats.
