| Fuel Heads – Used for Gas, Alcohol, and Nitro (Fuel) engines |
| Stared with original 426 bolt pattern alcohol engines only – 3 bolt patterns, but common intake manifold dimensions, |
16 Bolt – stock 426 bolt pattern, 2 bolt on each side of each port, uses a gasket (stock)
 |
 |
| 10 Bolt pattern – 1 bolt between each port and 1 bolt on each end ( often the bolt behind the Mag wasn’t used or was actually cut off of manifold and/or head) bolt , uses a gasket (stock), some had o-rings on intake manifold. |
WAR head with 16 bolt (stock) bolt pattern, and 6 bolt pattern.
o-rings between the old and new ( not all manifolds would seal properly. |
Note: these heads are both Dart Fuel heads, just made with larger ports on bottom head ( o-rings and larger ports would interfere with end bolts if they were use ) both manifolds would fit but may interfere with o-rings |
| 6 Bolt pattern – 1 bolt between each port , uses o-rings on Head. – just made with larger ports and o-rings |
Note:
Early Veney (FUEL) heads had there own intake bolt pattern “AND” Manifold dimensions, the head intake surface was machined at 90 deg. to the head surface . |
|
| Alcohol – Fat Heads– Brad Anderson Racing / MBE / Co-Line / NRE / Total Flow …etc. |
|
10 Bolt pattern – 1 bolt between each port and 1 bolt on each end. Looks like Fuel (10 bolt )
but does NOT interchange.
|
Stage 4-10 –> ?
designed for blown alcohol engines and A/Fuel – Unique intake manifold dimensions, fit most Fat Heads except “Veney” |
| |
|
| Alcohol – Fat Heads – Ken Veney Ind. |
 |
designed for blown alcohol engines – Unique intake manifold dimensions, But only fits “Veney” Heads
10 bolt intake – but end bolts are 90 deg to manifold surface, and intake surface is 90 deg from head surface. (o-rings on intake manifold.) |
|
Mopar – Steel / Iron
16 bolt intake manifold is a standard original Mopar intake bolt pattern, |
|
Note: the original 16 bolt mopar intake bolt pattern “and” the ” fuel” 6 bolt patterns
