Has anyone heard about this head brand? Racing Head Service. It sounds like they may perform similar to AFR and the 11* ETP heads.

"As part of the Pro Elite™ series, the new RHS™ Gen III aluminum cylinder heads are fully CNC-machined for consistent quality and maximum CFM flow. Incorporating a 0.800-inch thick deck surface (twice the factory spec) increases the integrity of the deck surface, making it perfect for high cylinder head pressure applications and creating a combustion chamber that can be decked to 36cc. Steel inserts strengthen the stud boss area, while casting integrity is further improved via the triangulated exhaust and hardened steel head bolt washers.
Raising the valve cover rail 0.500-inch allows for the creation of the raised roof port and allows aftermarket rocker systems to be used, without a valve cover spacer. Best of all, the RHS™ design team has re-engineered the valve placement, rolling it over 4-degrees from stock and creating an 11-degree valve angle."

Used to be back in the day they were one of the best, they went out of business (why I don't know) IIRC Comp cams bought them, and has just recently brought them back
BTW a set of RHS heads helped get 400 hp out of a 305
So they had a solid rep back then, what they're like now, who knows
