curious to see what you can do with the Trick Flows, I know they will be good, thanks for what you do here.

Blending the spacer to the manifold looks like thats worth some power all by its self, nice work !

John, thanks for your hard work and dedication to the small block Mopar as well as sharing this information with everyone here.

I am to old for that heat anymore, good luck getting anything done.

360-1 = Rectangular port , 360-2= oval port like the W2 port, see oldmanmopar's post above #5 for 360-1

Rumble is this the way they came from Hughes with any other modifications { valve job, port grinding etc. } ?

I wish you and your wife many years of happiness in your new home.

Kendall still in biz ?

Were these the heads that were for sale on here a month or two ago ?

You are going to need a loose converter, 4500-4800 or better and good sticky tires.

John you are honing your skills at block collections :thumbsup:

Nothing wrong with 318's, I have had a few that perform very well but, I prefer a 4inch bore for making power.

This could not have happened to a better Guy, Good for you John you earned it ! OH, and Boosted !

John please do not stop posting, you are a True " Hot Rodder" in every sense of the word, you are respected by all on this site. I know you have been extremely busy with customer's work and it is time you go and have some fun with that Bad azz Duster and get yourself rejuvenated. I for one...

So sorry this happened to you, hope you can get it corrected. Best wishes .

@Rat Bastid

Rat , What made you give up on the Hyd Roller ?

John, got a question for you, do you change out the exhaust valves to the Ferrea F6104 valve in a race version only or bare heads ? The reason I ask is that I have a set of Speedmaster heads complete with hyd flat springs { black Friday 2-3 years ago}. I will be changing out the springs...

I know you are extremely busy. maybe sometime in the future when you get more free time. In the mean time we will monitor how the 330 cfm heads work out on your Black Duster

330 cfm ! You going to need a race block for those monsters. LOL I may contact you for a set of the 2.08 heads. That is impressive .

Thats a very nice gain for a .035 larger valve and a competition valve job, I have to ask what happens with the .050 {2.080} larger valve and the 5 angle valve job ? Glad you able to use those springs.

Excellent for a Speedmaster 2.02, do you think the Ferrea 2.02 would be any benefit to the flow results ? When you add a 2..05 or the 2.08 valve does the port stay the same other than the throat and the bowl to accommodate the larger valve ? Thankyou John for sharing all this valuable...

John, mind if I ask, what is the name of the puddy you us to coat the brass tubing before you tap them in the head also what size drill bit to drill out the pushrod hole for the tubing? Thankyou very much, Red

OldMan, where did you get those valve covers ? sorry, Not trying to highjack this awesome thread.

the crank is a cast Eagle and he brags about spinning it to 7700 RPM, Dang !
