Awesome head. The best 23* low port available currently.... Makes great power and runs well -As my car shows. Low 5s and high 4s on street tires with a Cheater Plate..... Thanks for everything Chad.
Man I love your heads? I just pulled my motor and sent the block to the machine shop cause I got better Diamond pistons. I have Dart Pro1 215’s on my bench for it that I’m fixing the chambers on for the F1R Procharger I’m putting in as soon as I get my block back and the cam comes. Never played with boost before so I’m trying to figure out what to do to these heads. Wish you were closeer!
Chad Speier, when the cnc machine cuts around the seat area in the combustion chamber and throat area, do they have to slow down their feeds and speeds to keep from burning their tooling up?
Very impressive casting, and great work as always, will the RR profiler that you have listed on the site be even more improved in terms of potential to provide more horsepower than this one?
Hmm, is there any downsides putting a head like this on a smaller motor, or is the reaction of the head a relationship between the throat size and the volume of the port? Or somewhere in between.
Good videos Chad!👍 Chad have you ever worked on a Edelbrock 2858 Victor Glidden 15-18 Degree Spider Intake Manifold ? I got a set of Brodix 12/13 heads to go on a tall deck 436cid. Is there a better manifold out there now? max rpm 7800 to 8000 rpm. 🙏

Chad Speier, I appreciate you explaining about the wings. That is really good knowledge.
Very nice head Chad.
The work is very nice.
Impressive.
Thanks for sharing.
Take care, Ed.

Those ports are something to be proud of for sure
So shaft rocker setup is mandatory. What line of heads don't require a shaft setup and can use Standard stud mount?
Chad, do you have any plans of doing a badass big block mopar head ?
Awesome head. I know some people are going to ask about how to make sure that the intake gaskets seal between the intake ports?
A Mr Gasket 5824 fits perfect.

absolutely
@@SpeierRacingHeads I cant wait until you put out more information on them- when do you anticipate them being available?

That's what I'd use.
👍
Well send me a Pair, and I'll build a 10,000rpm combo for the Holden
