Depuis un petit moment j'ai remarqué ce genre de pieces sur diverses site ....



..... en fait des centreurs décentré justement de culasses et je souhaiterai savoir les avantages offerts par ce genre de pieces , en fait tout développement sur le sujet m'interresse .

bonne question...je vais me renseigner aupres d'un pote...

Offset cylinder head dowels are used to properly locate the combustion chamber over the cylinder. Factory tolerances can be way off the mark sometimes so do not take anything for granted .

if the are for the "b" motor heads they are to move the heads to place the valves more in the center on the bore. this way you can get a bigger valve in the heads and have less strouding at the edges of the chamber, like the sm blk moper has. if the are for the bellhousing they are to center it to the crank. this is especially helpful in a clutch car.
