Dave I just had a 318 2bbl & the crossover was not heating(should be able to put your finger on the crossover pasage & feel heat starting after several minutes) & I had opened up the carb(from hell) 4 times(not kidding) & it still wasn't right so I swapped to a streetmaster alum intake and an eddy 1406(w elec choke) & now starts excellent/runs fairly good after changing the metering rods one time. I left the clogged heat riser passages as is. imo Even though it looks nasty I would not mess with them(cant get anywhere near all of it out without taking off the heads to do it right & could loose pieces into the oil or the chambers with catastrophic results
Thats the problem, I was concerned about it getting into the valley and made sure that didnt happen, but didnt worry about it getting any where else. It ran OK, not great before, but it ran good enough. Now I am wondering if I need to pull the engine and just rebuild it. or at least the heads.

withRR leave well enuff alone you can change the seals without R&R the heads easy enuff when the engine is out I ran plenty of JY engines worse than that change the seals and button it back together and hope ya dont already have some loose carbon floating around on start up if $ and time are on your side then by all maens do it right and R&R them and get a valve job bet the exhast valves have pitting on the seat now anyways,IMO slam it and run it,I would! runwhatyabrung

Like said above most of your after market performance manifolds are blocked any way so it would be of no advantage to go through the work to chip it out and risk getting carbon spread through the engine.
Not so! My holley SD, Eddie LD340, LD4B, Offy etc have exhaust crossovers. Your Crosswind, Airgap etc. don't. We are talking about a truck here, not a racecar.
I run with mine blocked off on my 360. It is an aluminum intake. It is OK even down to 2* But that is aluminum! Not iron! Gonna drive in the winter up there in Idaho, and Northern Nevada with an iron intake? Do the job right.
I said most. And I know for a fact that my LD340 is blocked (cast) and has no choke well accommadation. How hard is it to look at the intake and make sure? Also very easy to put an electric choke on and it will help emensly Not perfect by any means but they do work.

I can do that easy enough, thats no issue. i am more worried about the issues I may already caused by drilling out most of the crud. If I am safe, then buying the correct manifold to make it better is no issue. I just dont want to have to replace the engine or get into any major cost factors like doing the heads. But at the same time, its exposed and easy to get to, before I put all newly painted sheet metal around it.

Moparforlife aluminum as I am sure you know will warm up lots faster than an iron one. Especially with hot oil splashing off the cam. That is why my Offy is plugged on my work van. Dave I've never seen a Mopar head that didn't have sloppy guides. If you have it apart might as well do it right. I am going through this same stuff on a slant that lost oil pressure. I looked at the cam when replacing the crank and bearings. Lifters look fine, lobes have weird looking pits. Changed water pump as the factory one was still there. Doing the freeze plugs, new oil pump, pickup, timing chain etc.........sometimes things snowball

I have a question, whats R&R stand for? and the seals you are speaking of, can I do those as it sits now, or are you talkign about removing the heads and redoing the valve seals?
Thanks dave

R&R is remove and replace If the timing chain has not been replaced now is the time to do it and be safe. I would highly recommend it. Sorry about my previous posts on the intake cross over. I thought that I had read that it was an aftermarket intake you were putting on it. I would definitely use the composite type gaskets on it though not the tin ones.

take a vac to the plug hole on the 2 cyl that could have gotten some carbon in them and turn the cranck and push the piston up and suck any thing in there out slam it together and get er done I would put a t-chain it it for sure while its out,I slam the 2 back freeze plugs in it also,just look at the rest and change if needed while the intake is off and the dist out see if there is any play in the block bushing for the itermed shaft...most the time I pop a new one in just cause it in the whole core plug kit I R&R the oil filter plate and replace that gasket and drill 4 more holes in the plate for good measure clean,paint it with 3 cans dupli coler hemi orange,talk to it,cut/smash knuckles and bleed right in to the engine for mojo to the mopar gods,cuss alittle,dance a jig holding a rattlesnake and bible and oh!!! my bad,,got carried away runwhatyabrung

If you want that thing done and are wondering about the stem seals,(looks like the heads have been off at some point), you can poke the seals with a pocket screwdriver through spring while the v/cvers are off to find if they're soft still or rock hard. It will give you a quicky piece of mind. Or are ya done already?
POKE WHAT? OK, what seals are they, what do they look like. I will check them out.
No, not done, got too frustrated and went back to what I know and started some body work ont he tail gate, radiator support and bed
and put doen some primer on a chest style coke machine that I a making a cigar humidor out of.
