Hypothetical head ideas

Breaking Habits · Mar 12, 2014

I think your biggest issue is going to be that making a new billet camshaft isnt even remotely cheap for one move. Also, that would probably rule out any stock appearing turbo set ups, not that it matters.

I'm probably pushing as much as anyone else is for the new head situation, as my new motor needs heads that flow as much air as physically possible. Just making the situation happen is another story

What, in your opinion, is the biggest factor preventing this from happening (expense, small demand, space limitation, water jackets near the runners, etc)?

For one. Most shops are way too busy to try and figure it out, or dont have the overhead to money up the engineering costs. Demand is such a small factor, and in reality, how many tire kickers will you have at 5-8K for a set of heads. Not many people will actually money up.

Thanks. That's what I meant by small market. A lot of people would be interested, but probably not of people willing to pay $8-10k for heads. I know any product development takes some initial investment and I figure heads have to be one the most expensive ones.

Ok since these dreamed up heads would probably only ever be put on a dedicated competition truck, lets say just for arguement sake they are solid without waterjackets to eliminate some of the engineering and make more room for larger ports to be cast? And if they ever took off then worry about casting some water passages for more street friendly trucks.

The way I was thinking about it would keep all of the stock valvetrain components from the cam to the valves. I know they would be expensive but any head option would be. And I really hope to see your truck with a nice new billet set on it someday:evil. Its an animal now!

This was in response to a 6.7 style head with inverted flow. The cam would be a completely different profile to do intake/exhaust backwards essentially.

Know what'm sayin?

Yeah I get what you are saying. But I just didn't know if you knew what I meant about just moving the ports to the opposite side of the heads to retain the intake and exhaust valves as intake and exhaust valves.

Exhaust and intake valves are different sizes. You would be way down on efficiency just reversing flow.

If you want to do anything with a stock head imo mill the intake runners off and go from there.

Ill post up some pictures of this today :jammin: :nopics:

Me and kevin have talked about trying it our self we just need some equipment first.

There's already a picture of something like that on here... I think sonicsuperduty is doing it to his 6.0 puller

Ya he has had that thread up for a while.

powerstroked08 · Mar 17, 2014

Well that would be cool to see. I would assume you can still only go so far with the port size but by making the runner shorter you will gain a large amount of flow. Is that correct?
