    Can anyone please tell me what heads these are? Was told they are a set of Mike Chapman heads??? Came with the motor. Motor was in a crate and was told dyno time only after build. Everything appears to be true to what the owner said. I can’t for the life of me figure out what heads these are???? Only things I can find anywhere on them is on front there is a stamp that says “trick head work” followed by the numbers 477277. On the rear corner there is a 3 stamped and on the exhaust side only thing stamped is a 619. upload_2019-11-28_14-5-18.jpeg
