EQ Magnum cylinder head, Amature porting, Stock intake valve flows

[@grahamm3559]

Looks like he did a good job of cleaning them up. I am looking forward to the next video and maybe some Charlie insights on further tweaks that could be done by the average Joe - if they were brave. Laying back the SSR a tiny bit, pushrod pinch etc.

Thanks

Great call on the manifold. Of the options you said the 340 is definitely the right choice for a road warrior. It's actually a good choice for almost any small block Mopar short of drag or circle track engines. The old school 5.6l was a banger for its displacement.

@@jseal21 It is a great design!

[@luckyPiston]

Hot Rod mag did an article on these heads back in 2017 , the EQ's bettered the stockers by 2-3% , here the customers porting added about another 2-3% again so these heads are about 6% over stock.

[@servediocylinderheads]

@@luckyPiston Good info. Thanks!

[@v8packard]

Were the heads in the article the original New Zealand cast EQ heads?

[@servediocylinderheads]

@v8packard I did both

[@v8packard]

@servediocylinderheads I thought so, thank you. I thought the magazine article was probably about the New Zealand cast heads.

Thanks for the video Charlie! I'm on to the next one ,lol .

Great to see you back on these !

[@servediocylinderheads]

@@nickstephens2913 These are another set. Testing only on these. Thanks

Man those Pushrod Bulges take up alot of room flow in Charles. I thought it was bad on sock Pontiac V8 Vintage Iron 1967-79 D-ports exhaust. Its opened up generous on my 1970 RAIV casting #614 Iron round ports. Magnum EQ's aren't bad actually good foundation. Looks like the higher airspeeds may be due to the Magnum EQ pushrod bulges ? Still waiting for you test Pontiac Vintage Iron D-ports. No one On You Tube or Vizzard ever tested and published results. Air speeds, Swirl, and Flow numbers in order of magnitude importantance.

[@servediocylinderheads]

@@brracing7861 I haven't done a Poncho in decades. Pretty tight through the pinch no doubt. Thanks

[@jseal21]

All Mopar castings are ridiculous through the pinch. I can't remember the casting number but some of the older closed chamber SBM heads are so tight you can barely squeeze a pinky through the pinch. I have pics but KZbin won't let me post them.

[@servediocylinderheads]

@jseal21 My Mopar buddy in the 80's said, "The ports are so small they will make you cry!"

[@DusterCI]

Thanks for the video and info.

[@servediocylinderheads]

You are welcome.

[@juhanahuovinen]

Thanks for the video. 😊 It just occurred to me that a wire brush doesnt smell, but acetone cleans the dykem residue in no time. What do you think the intake noise is coming from if it starts at 0.3 inch lift? -juhana

@@juhanahuovinen ssr. Thanks

[@briantayes2418]

That seat needs to move further out to the valve edge. Seen at 4:23.

I have 4 cyl 1.5 it has 2 type head one of them has bend on middle of port but the other head hasn't bend and stright to the center of cylinder i want install supercharger on it and i want engine rpm goes to 7000 what head i choose to have good performance Thanks

[@servediocylinderheads]

@@amirdoshmanfekan5145 Darin Morgan states he wants one turn in a port instead of a curve.

[@luckyPiston]

Looking at the intake velocity numbers 6:09 in particular the SSR velocity relative to what's happening there and what's happening upstream from there at the PRP , my immediate thought/observation is that not all the air flowing over the SSR is coming from the lower (slower moving) PRP , Or is it ? ... My question is what is your observation in general as to what will happen to the SSR velocity if the CSA at either the top or bottom of the PRP is increased ? Which in your experience effects SSR velocity more , opening up the top or the bottom of the PRP ?

[@servediocylinderheads]

@@luckyPiston D.V. likes to add area to the top of the pinch. I tend to add area dependent on air speeds

[@Patrick-xd8jv]

Thanks

[@brokentoolgarage]

Nice!

[@servediocylinderheads]

@@brokentoolgarage Thanks

[@robertwest3093]

I thought the Ford E7 head had a narrow pushrod pinch. The Dodge small block head has a huge bulge and it all comes from the one side. Is there any room to grind some of that out of the way to open the port up? I don’t know how thick the casting is there.

[@servediocylinderheads]

@@robertwest3093 I worked up a set of these a while ago. I did a whole series of videos. They finalized quite well but lots of sonic checking. Thanks

[@TheProchargedmopar]

I'm thinking about buying some from china, Only $500 ish a set. 👍💪

[@servediocylinderheads]

@@TheProchargedmopar I don't know of another Magnum head than these.
