i have the Edelbrock rpm air gap and TBH its a SWEET looking manifold but i wish i would have gone with the regular rpm manifold.... im pretty sure the "colder" charge you get leaned out my A/F ratio, its a pain when you drop a bolt or nut in that area.... if you have an oil or coolant leak anywhere near it, it will collect in the valley. also hood clearance could be an issue with it.

If you have a good punch sometimes you can shatter the broken piece of "easy out" and blow it out with an air gun, its a long shot but it has worked a couple of times for me.

if you don't mind, how did you figure that out??

another reason for the low profile TorkerII manifold is air filter to hood clearance,
the RPM will probly be taller..

I ordered the 7161 oval port but now that I took the old one off I am a little concerned . I do have oval ports but not sure about where the smog port was blocked off. Hoping I ordered the correct one.

Hood clearance should not be an issue as I have the cowl hood. When I checked it looks like i will have plenty of room.

How I figured it out... It was several cross references from different sources using casting numbers on block, heads and partial vin.

yea, there are different size Oval ports, but there still Oval ports
you want the head port equal to or just slightly larger than the intake port,
smaller causes more turbulence, not good for air flow..

edelbrock 7161 Port Exit Dimensions: 1.60" x 1.94"

but not sure about where the smog port was blocked off.
as for the heat riser ports in the head and intake, depends on the driving style and maybe the climate..
if its a street/driver car, i'd leave them open, for faster warm-ups, depending on the carb/choke??
and you have to have a working heat riser/EFE valve in the pass side exhaust for it to really work right..
for a drag car block them off..
.
.
x2 on the drop base air cleaners, but theres a lot of different heights out there,
and some don't work with certain carbs.. motor mount height makes a difference there too..

..
...You can tell what heads are what,just by looking at them too,
for an example, one hump is rectangular ports, no hump big oval and penut is a two step mark,on later penut port heads,76 and later they change the two step and put it upside down.









..penut port heads I.D. mark..
..up to 75-87..

....78-87..

Yes luckily It all matches up as far as port size. As far as the exhaust goes the gaskets have a square hole in the center and it also matches up but the gasket set came with 4 square pieces of metal each with a hole in the center. That matches up to the size of the square exhaust hole. It seems as you match up 2 together one on each side of the gasket and bend the tabs to lock them in place. the existing set up had the exhaust holes completely blocked off at the head but those came off as I was cleaning off the old gasket material. The blocks were starting to rust thru so figured it was best to eliminate them. It kind of looked mickey moused to me.

Another question..... from the videos I have watched it shows to only put the rtv gasket sealer around the water and exhaust ports only. It is obvious that the old ones had sealant around every port. Any insight on this???

yep, that's the way you do it,, they should have some instructions with them..
.
.
set the intake on with no gaskets or sealer and check the fitment,
if the intake to head surfaces are parallel?? I don't use any sealant on the intake ports..
I use hi-heat RTV on the water ports and end seals..
I do not use the rubber or cork front and rear end seals, I use RTV on those and let it dry for a while..

old thread but it helps to use catapillar anti lock when bolting steel to aluminum
1 can last a life time use it any time you use steel bolts on aluminum
aluminum rims lugnuts tiny bit on radiator holes before steel tranny lines
torks better breaks without yanking aluminum threads out static electrollises
in motor spark plugs grounding through engine and not to dog aluminum heads
but they will deterierate if you dont drop electrollises dohicky in radiator freind rod hall racing even bolting steel to steel or other
every bodies broke a lugnut before
peterbuilt frames actually start peeling like rust on old steel
supposed to use special kind of bolts
torked bolts on tractors as big as your car tires before
cant remember
but it sells a lot of parts lack of knowledge
