FH high dome heads NA

[3W Hank]

I has a question.
Few might not get my ideas ( if you read my posts ) on not ’need’ HP but still stubborn try to find some in a combonation and not go max cubic or to a blower.
But most will not understand why not use a Chevy SB and a 5 speed.
I’m no fan of Cadillac, early Hemi etc either, so in this case it’s a NA FH.
This is the 40’s style.
Before I thought Ardun was the way to go with a blower, but I just love the FH heads in steel or Navarro, Harrells or Edmunds but I brake a leg for set ORD’s.

I will get a search on a Edmunds set as I like that idea he used.
Feel Very classic to me.

-But over to topics.
I has not a problem get me high class rods ( I has sources ) and CP pistons, but I will use a Merc crank as I will nog install China steel in my 3W ol’ Henry Hot-Rod.
I will use my experiance from stock eliminator racing.
-Worth the gain, maybe not.

As I mentioned I asked H&H on the high dome heads they sell.
Even if they get 30% extra flow it might be 5% better out in exhaust (?)

Now the question.
Why is a high dome better ?
Say the same CC ( 65 )
As I been told this engines had not much gain in what so ever design in heads, but ’maybe’ sparkplug locations might help, but Navarro did not move the sparkplug in his high dome heads.
-Did he not see what Edmunds did way back then ?
Or was it no gain maybe.

This heads is told get HP, but it was said ; no one had afford to do it, test it, dyno so Barney had no info on it.

So is there any idea why high dome might be better.
I do note it’s a step for the valves in head, so a cam with less lift on exhaust is needed.

My guess most just use a blower instead and forgett about this, but I think it sounds intresting.
