Probably are discontinued since GM is offering the Vortec Bowtie heads which are light years over the older Bowtie heads.

I have 1 head new. It is out of box but has never been touched. I would like to give it a new home.

Firebird…Try Reher-Morrison's. They might have some "upstairs". Good Luck…MB.

What pistons can i run with the vortex heads----i have Mahle dome pistons with my rotating assembly. Is it wise to machine them to fit?

Firebird, an experienced machinist will have a fixture to measure the piston dome/top thickness. If you can machine to the needed dimension and have enough thickness remaining it will be fine to do so.

I "think" it has been said the Vortec is best with very small or no dome.

I do not know the min thickness needed but figger someone will help with that.

thanks for the reply ---maybe i'm to old to take a shot at this class---would a different set of pistons be a better option ? i want good compression ratio--THANKS FOR THE HELP

Firebird, what are your plans? What class and buildup details?

You can use the large port Bowtie Vortec cylinder head or the approved Dart Cast Iron head.
