Sbc brodix -10 spread port head i.d.

I need help identifying a set of SBC brodix heads. I purchased a set of brodix -10 spread port heads that were on a 410 sprint car to use on a project motor.

The heads are stamped "seconds".

The numbers stamped on the end of the head are 10 AB 502 557 & the other head is marked 452.

The intake valve is 2.05 diameter.

I looked around on the brodix website with no luck.

Thanks in advance.
