Default I got a 402 built with afr heads, questions

And i have AFR 205s on my current stock block. I should be able to open them up some to work on the 402, correct? I saw tony mamo mention using 205s on a 402 and getting 560rwhp out of them.

Do you have to open them up to get them to work? If not, how much of a choke will they put on a 402 if I do not open them up? This 402 is a low compression motor for a twin turbo set up.

You should be able to use those on a 402. Contact Tony for details; he will tell it to you straight. I recently had my 225's reworked by Tony. He does excellent work.

Would make great torque. Probably want to have the sides of chambers opened up to match the 4" bore. it would unshroud the valve and promote air flow.
