Help:

- 6T 1952;

- T110 1954 iron head;

- bored 0.20;

- base gasket steel spacer .040;

can I use 9.0 pistons ?

Thanks

Sure. I assume you mean standard unit 650 pistons? They will work fine, although they will net you less than 9:1 due to the difference in the combustion chamber design of that pre-unit head. If you take apart most pre-unit 650 engines in use today you would likely find that most of them are running that piston.

shaggy's right most P/U irons run them, but you also have a .040 de-compression plate below the jugs? you don't really need that.

I thoug a base gasket steel spacer was to needed for the difference in the combustion chamber design

I see no need do that now.

Thanks tony and shaggy
