Question for the guys with cnc’d Speedmaster heads

[pittsburghracer]

Or at least those that got heads with cnc’d chambers. What size head gasket fit the chambers. Any pictures

Here's Felpro 8553 measured at 4.175. Centers up pretty nicely on the 4.085 Speedmaster CNC chamber.

Thanks for the picture. They pushed the intake side out there pretty far.

Let me know if you want more pictures. It's sitting right beside me.

No that’s perfect. Probably 4.120 give or take a little. Thanks.
