Edelbrock Heads for 318
MAN! I'm late to this thread
These type of answers is what got me started on a 318 Duster project.
321Scamp, I'm starting with you from your first thread.
The Edel. heads on a 318 can be use no problem, but your comp. ratio is to low. The cam and intake you asked about is to mild and best used for a stock headed engine. Actually, it is in my opinion you use the cam for a door stop. The intake is good. Go to Huges for a good cam for the teen. Comp and Crane also make nice split duration cams for a few bucks less.
Otherwise, there a bolt on and in deal.

Heads are bolt on, no maching needed. The 273 can not take a 2.02 I'm sure, but needs a notch for the 1.88. C130 Chief and perfacar hit it on the head good. Moper covered it on a how to install the Magnum heads if desired.
IMO, it's your choice on the head.
I myself can not understand why the stock head "Preped" wouldn't do it for you. Even smog casting well preped would be nice and pocket porting is still a good move and gain. By way of the intail cam choice listed, A Performer, the build is very mild. Very.
Did you mean a RPM cam? I'd still leave it on there shelf.
Alot cheaper than edel. heads and performance gained.
You have to figure new heads and bolts vs re-using the old heads milled a tad for a good ratio. The iron will keep the heat and the skinnier ports will keep velocity up. Just what the teen needs. Unless your going for broke.
But this hole you want to drill, (?) YIKES. You want to add a heat riser for the cold right?
I'll have to show you this. It is a stock 340 (73) aircleaner on my 400 B engine and the heat stove I added. Do this and you'll be OK. All it is, is a peice of sheet metal cut to length of the headers pipe, bent in a tight U shape. I cut 2 slits on each end for worm clamps (Like for the rad hoses) that wrap around the header pipe and keep it high enuff to create a cave like area. This mimics the heat stove. It hasn't failed to do it's job yet. I've only been to 30* in the morning. Theres a marked difference in warm up time on the big block.
On a exhaust manifold, passengerside, theres that flapper valve design to force exhaust back up and through the intake manifold. You can duplicate this. I *think* it's Hooker has this very part designed for headers. It bolts onto the collector.
OK brothers and sisters, ttyl.

Mike, he's asking for help with a 318. While your comment has merit, it does not answer his question at all. He's also saving the purchase price of the engine. 1 or 2 benjis could be alot to him. Why get behind the 8-ball from the get go when there is really nothing wrong with a 318?
