What are these heads?? I have read they are the etp head and that they are a dart head. Some I have seen with 2.05 and some with 2.08 valves.. Some are 600 dollars a head and some are 1400+ dollars a head.. Is it from being cnc ported? and has anyone ran these

Older rhs heads were made by etp. That is the one to get.

The mags have been using RHS LS1 ascast heads lately with good results. IIRC. they were replacing stock LS1 (241) heads though. I'd be interested in seeing a direct comparison of stock 243 VS. RHS heads.

You would think the company that owns the basic aluminum rhs lxs block would have some decent "their casting" heads.

Still no info on these? They look like they would be a good start to a very nice ported head

I can tell you flow numbers mean ****. My cnc ls3 heads out flowed my tfs 235 heads but i still gained 20hp and 15 tq and went faster in the 1/4mi. Why use this rhs head when trick flow and afr have been proven with many,many combos.
