Are ported TrickFlow ultra 18 degree 250 comparable to bowtie 18

[bosco]

We have a road race late model stock car for SCCA SPO (run what ya brung) class. Starting to have issues with the Chevy Bowtie Nascar 18 degree heads ie: cracking. While we can have them reparired, this stuff is 20 plus years old.

Was looking at the Trick Flow Ultra 18's as an alternative.

Does anyone have experience with these and could they offer similar performance potential in a cnc version in a road race application?
Thanks for any help

Yes.
I have done several for customers that switched everything over from their 363 castings.
They have an updated casting and its very good.

Thanks, being able to use our components is huge, and it is quality pieces.
