Running a set of stage 1 Hughes on my 360 Duster in signature for about 5 years now. No problems at all and perform well. These are NOT reboxed heads.



looking on their site, they sell "sportsman" heads, which are rebuilt OEM heads. everything else they sell is either work done on your heads (or core heads from them), or aftermarket replacements. their "Iron Rams" are Enginequest 318A/B (mag/la intake), and they also sell RHS heads.

Nobody said that these weren't rebuilt on used cores. Mine are on 587 cores and very happy with them.
