Where does the 79 bus cylinder head come from?
Note: the 79 bus cylinder head is one year only. Although it shares the same square exhaust ports with the Vanagon CV engine, the valves are not the same size. Casting part numbers are nicely covered over at Type 4 Secrets Revealed. You might discover that your head came from a 70-76 914, 1976 912E, 69-74 411/412, 72-79 Bus or 80-83 Vanagon.

Can a 305 cylinder head be ported into a water jacket?
These heads will port out well, but be aware that 305 heads have smaller valves, so only look for 350 heads unless you’re specifically working on a 305. This will save you the expense of extra machining to put in larger valves. Also, if the porting technician is too exuberant, there’s the possibility of porting these into the water jacket.
What causes valve shrouding on a small block engine?
Valve shrouding caused by the close proximity of the bore walls (red shading) or the combustion chamber (green shading). If the casting is thick enough, combustion chamber shrouding can be dramatically reduced. The down side is the chamber volume gets bigger and may end up too big for the CR required—especially if a stock CID is involved.
Where is the intake manifold on a V-8 engine?
The intake manifold has mounted a side of the cylinder block in L-head engines and on the side of the cylinder head in I-head engines. It is situated between the two cylinder banks on V-8 engines.

When do exhaust gases pass around the intake manifold?
When the engine is cold, all the exhaust gases pass around the intake manifold. When the engine is warmed up, a part of the exhaust gases goes around it, and when the engine is fully warmed up none of the exhaust gases passes around the intake manifold, but goes directly to the exhaust pipe as shown fig.

How does the damper work on the intake manifold?
The damper is controlled thermostatically to deflect the exhaust gases around the intake manifold. When the engine is cold, all the exhaust gases pass around the intake manifold.
