Exclamation any dyno info on the new afr 245cc heads?

im building my 427 ls1 mid shortblock and im looking for a set of heads. i think these afr heads will be great for my setup. which im aiming for in the 550rwhp. this engine previously made 525 and 489 rwtq on a mustang dyno with the lg g5x4 cam and the 225 afrs.

Pretty sure they are 240cc. AFR rep said that it would be a couple of more months before tey are coming out. I was thinking about running these on my ls3 build.
