Which flange head or turbo ??
I have the head flange, no holes in it,
$30 which is what it cost me to have
custom computer flame cut.
as far as Turbo Flange I do on a case
by case basis, I saw a turbo today, speak up
quick and I'll get it and ship it for you, $100
and it's the one I wished I used, better design
casting for the engine compartment.
