Do you think a EPS is ok for my combo, or a RPM Dual Plane?
With those heads and being a street cruiser as you mentioned, i pick the eps. They respond well to a .5" open on the intake then .5" 4 hole on top depending on use. Great intake and cheap!

Eric port matched the EPS to the 1205 gasket, like he did the Dart Conquest heads. The RPM dual plane I have is not port matched.

You think the even if I have a redline of 6000 to 6500 the EPS will be better?

I had a 67 Camaro with a similar setup. My favorite upgrade was going to a TKO-500 5 speed with an overdrive fifth gear. Made 70 mph at around 2500 rpm's.
Dang! You nailed it with the 67 Camaro reference

Your previous wild azz guesses without even knowing the cubes, compression, engine architecture, application or anything else was reeeaallyy close though
I don't follow you on what I guessed on?
I'm not surprised

True street and if mine i would run the eps still, yeah im going to use it to 6/6500 but realistically WOT in the stall rpm up to 6K is going to do the most for me on the street and at part throttle cruise the eps is best.
If you are going to port match then use the RPM, i dont want to open an eps out to 1205, the rpm has a little more runner csa and port opening area so going to 1205 is not as big a deal.

I don't have a auto. I have a 4 speed.

I follow on the EPS and 1205.

P.s. if you already own an RPM just use it. The differences are hair splitting

Its not my car. Its my Dads. He does not hardly spin the tires in the car. Just the occasional blast up through the gears to like 5500 to 6000. Probably not even using all the cam or heads.

I can swap them out and see which one he likes better.

Go the eps, if you have room try a few different spacer combos.
Once you have it where it works best then try your RPM

Ok. Sure well. I have a variety of spacers from 1/2" to 1".

Op / DV, What are ambient condition, is it practical to keep it at 170F all year /driving season?
What is pump fuel consistency like in the area?

DV, those. 006" & o/lap figures suggest an idle that will rumble the china when the OP cruises thru the old folks home driveway! Im interested to see the .050 & .100 numbers.





the idle quality is defined by the vacuum so - with the vacuum down to some 14 inches yes it will rumble but not that much.

Different figs to cam mentioned earlier or is this the basics on the most agressive of the available profiles?
Edit , typo!
