Anyone actually running 5.2 heads?

[Schwerin]

I've seen a few people selling 5.2 heads to use on the 5.0 but I cant seem to find anyone actually running them. Just wondering if anyone is.

I do on 2 cars with 5.2 CP short blocks .

I run them with my 2015 with Hellion TT and GT 350 intake . Now with RPG built 5.2 short block

I also ran them on my 2015 KB car before switching back to GT heads . I will be switching back to the 5.2 heads with new long block

Also just had another 5.2 block built by a BPS with the heads

Best to run them with the recommend Ford Racing cams which need the 5.2 rocker arms .


I don’t think they work so well using the MMR rocker arms that allow the use of stock cams .
