TTT anyone? I know this heads are perfect for boost application but I'd like to get them shaved and use them for an NA application with 11.4 SCR

That's a good question b/c milling them .07" may be a bit much...

you can mill them as much as you want but any thing over .050 will require machining the intake seal seat to match the angle of the heads....
