HHP Racing CNC Ported Cylinder Head Pair by BES Racing Engines for 6.1L Gen 3 HEMI
How does this process go with your stage one heads? I'm looking to install a comp.cams.hrt stage two non vbt camshaft. 592 intake, 583 exhaust lift, in a.2005 5.7 block and have these 6.1 heads installed as well. These have the 1.55 exhaust valves in them and from what I've seen, the exhaust side is a pretty good sized bottleneck and flow isn't that great. I race and show this car quite often during the season. I run in the mshs race from time to time when my schedule allows me to. I'd like to have something planned for the 2023 racing season and seriously move up the ladder with what I have now. Car is a 2005 dodge Magnum rt. Unopened engine, all stock except for colder ugs and after market coil packs, and a custom true cold air intake tube with cone filter. Car has run a 13.349 at 103, on nitto Motivo 255/50-18 tires, on the stock drivetrain and open ended 2.82 rear. I'd like to eventually see about 490-525hp out of this motor before the stroker kit gets finally put in it. If that's a possibility. Looking to use the 6.4 intake and see a window switch to activate the runners in it. I need specs on the heads you provide that would be a good fit for my application and hopefully budget too. Also planning on buying the bullet and going with large tube (2") headers and a full 3" custom exhaust (which will be an upgrade to what I have on there now which is a full 2.5 exhaust with an x pipe, and two aeroturbine 2525 mufflers. My upgrades for this coming season will be all drivetrain related in hopes of high 12s in the 1/4. (2800 stall, aluminum driveshaft, getrag rear with posi diff and ,3.23 gears, 6 speed axles and hubs, and using drag radials on race star wheels. Please let me know how this works, and the price that's listed for the stage 1 heads, if that's for each head, or for a pair.

Thanks for your extensive question. This unfortunately is something that cannot be easily answered online, rather we will request that you call in and speak with our engine department since flow numbers on these motors means very little when it comes to how fast they run in the quarter mile. Give us a call at 888-894-1115 M-F, 9am-6pm EST and we'll be happy to help get your build moving forward.
