I havent found my answer in the search.
Any help would be great , this is the last part I need to order.

Just got my 243 heads back for my LS2.
I had them ported and will be installing a 1900 tvs with them.
They milled them 3 thousandths to make them flat.
Would cometic gaskets be a good choice?
Which compressed thickness of head gaskets would be best?

Thanks
Tim
