Will they be good for a stock block 360 Mag.... maximum 500 horsepower. I found a set for 560 plus tax , shipping , Bare. Is this a pretty good deal???
I'd get them from Brian H, ready to go.
All the numbers you're seeing floating around that these heads produce are on his engines done his way is the logic. He puts good valves in them, much better springs and does very good machine work on them. They are truly ready to go when they leave his shop. I wasted time even taking them apart to check them.
Results..?
dusterdoug is running in the 10's with them on a 360....
MadDart made over 500 dyno'd hp with them on his 410 stroker...
Brian at IMM ran in the 10's as well with his sb n a duster.....
Just be aware when buying them bare & who from, by the time you spend for shipping (because there heavy)
I had Summit price match them for me. They sent them to me without charging me for shipping, not sure how that happened but I'll take it. I also had a $200 gift certificate too so I only ended up paying $360 for the pair. 8)
Here is his website. He is also a member on here. He is a great guy

I will find his post about the rhs heads on here

His website makes me think twice about buying high end parts!
I would love for him to build me a long block with those RHS heads!
Well not everyone knows how to design professional websites and besides he builds engines not websites
I and a lot of other people on this forum have been to his shop and met him so i wouldn't worry.
Don't judge every company by their website but i do know what you mean
Sorry, you misunderstood me, Love the website, it makes me feel more confident about his work not being all fancy! I was referring to not needing expendo parts to go fast! referring to his 10sec Duster with stock internals!

Here are a couple of videos of his car running with the 410/RHS from the car craft article. My guess is corked up it was making in the 470hp range. Pretty impressive run for an engine with "Iron Doorstops" for heads as some jackwad called them on here.

The car had a Hughes 10", 3500 street converter in it and went 1.43 60's. Not bad for a car with a cheap converter in it. I would have liked to see what it would do with Brians A-1 race converter, probably in the 1.3x range.
