Ok heres my plans for my 318 build I have my 318 and this is what I want to do I have stock 318 heads on there,80s unleaded stock heads,Im gonna be running a stock 340 cam,4 barrel single plain aluminium holley street dominator intake,4 barrel holley carb (dont know but I need a new carb),headers,new timing chain everything else new.waterpump,gaskets, stuff like that. So Im wondering Is it worth putting magnum heads on this from a 1992-2000 318/360 magnum heads on this and of course the intake that is special for this setup and the different pushrods. So does anyone know a price on that "magnum" setup.I know I could find the heads at the boneyard but where the intake?mancini racing will have the pushrods Im guessing. So any other suggestions for this build. Please guy don't rag on my underpowered 318.its all i have haha thanks moparts rules! P.s what is a good carb for my setup (brand,cfm,etc...)

I think the crosswind intakes are ~ $175 or so & dont order the conversion pushrods for this conversion until you mock it up as they have been reported as being too short.

Going with Magnum heads is totally worth it, they beat the snot out of stock 318 heads. I believe you need different length head bolts to use them, though.

do a search on ebay for crosswind...
that probably where the best price is going to be.

the archives has a list of the extra's you need. rocker arms, pedestals, guide plates, head bolts, spark plugs most all lifters have the oiling hole in the top now, possibly can reuse LA valve covers MAYBE different intake bolts/intake gaskets. Rocker arm ratio is 1.6 insteaqd of 1.5.

Those heads would be OK for a mild 318 build. We just installed a pair of them on a 99 durango at work. They are made in China and it is very aparent when you see there quality in person. Actually the casting quality was horrible but the machining was good. They had smaller chamber than regular magnum heads but also smaller ports. As a matter of fact I CCd them while I had them to make sure my eyes were not fooling me. I also checked a couple other sets while I was at it and pulled out some numbers from previous stuff I did. Head Brand, Chamber CC, In. Port cc, Ex. Port CC, In. Flow @.500 Factory Mag. 64 172 62 212/209 RyanJ/Hughes Chinese 58 136 64 RHS Pro Topline 63 182 67 Edelbrock Mag. 58 176 75 249/231 RyanJ/hughes Engine Quest 62 174 65 227 Hughes R/T 63 239/247 RyanJ/Hughes Mopar alum. 52 I will try to remember to CC my aluminum magnum ports this week. The CCs are my findings and flow numbers are Intake @.500 lift and whos bench the flow is from is listed after them. I made them a nice chart when writing in the little box but it won't let me do it on the real screen Been a while since I checked the R/T and I can not find the port sizes, mabey some one else has that info. The chinese head a horible casting but for a very mild 318 the smaller chambers could help out, that was the only bonus I could find to running them, the 318 Durango didn't like them over 4000RPM. The R/Ts have rough castings but they look very polished next to the chinese ones. For a cheap set of heads the EQ is a better one and you can get them with a warranty for about the same price and you can get them with a LA intake bolt pattern so you can re-use your intake. The RHS is discontinued but they are super nice heads, I have a brand new pair I will sell for about what an EQ or the Chinese head would cost and I will put the LA intake pattern on if you want. PM me if interested. The R/T and Eddy mag are slightly better flow wise but a lot more $$$.

You guys type fast The Alabama cyl, head ones listed are the chinese ones. The above link to the clearwater ones are re-man factory heads, don't forget the $100 core charge, at that point you just as well buy the EQ from them or the RHS from me. http://cgi.ebay.com/ebaymotors/NEW-CHRYS...emZ370142191074 That is the best price I know of on the EQ and that is just stock springs. The EQ R/T RHS Mopar alum. and Eddy have pressed in seats, the factory ones are induction hardened and the chinese one looked like there was no insert.

Sorry, those might be the chinese ones, the price was higher when I bough my EQs from them a while back and there was no core. There is a core required with those in the fine print. That one has the right pic but sounds fishy. Call them and ask, they were very honest with me about the quality of the chinese one. I can not find the regular EQ on there any more. You can get heads from a JY engine but be careful, the induction hardening process cracks a lot of them. If you buy from a JY make sure you can return them if they turn out cracked. JY heads should get new valve seals, better springs and valve job at minimum in my opinion but this makes them as much as getting EQ heads even the more $$$ one here http://cgi.ebay.com/ebaymotors/NEW-LA-EQ...emZ370124447607But you need springs with that one also so this one here should be ready to go with good springs. http://cgi.ebay.com/ebaymotors/NEW-EQ-MO...emZ370140468788I think I got my links right this time
