What material is the seats made of?

 

[Gremlinsteve]

They have some copper or manganese in them cuz they copper color in the cut
There not a cheap seat that's for sure

311 cfm @.500 lift. Damn. I have a few sets of old mopar heads that have been touched by the best guys in the industry that dont come near that... lol.

What heads do you have? I have a set of B1 originals that do 417 at .750 or .800", but I don't know what they do at lower lifts.

Scribing chambers

 

[Gremlinsteve]

Local ford dealer just couldn't understand no matter how much I told them why I only wanted one head gasket

 

[Gremlinsteve]

Polished chambers. Getting close to being done

This thread reminds me of two things:

1. How long it's been since I ported/polished heads myself.

2. How much porting/polishing heads sucks.

I do miss flowbench work though.

 

[16MustangVet]

this thread makes my pants tight lol.

ported heads such an art and still worth doing if you have the talent tools and skills to do so.
