> Looks like the CHI are 2.07" intake and 1.61" exhaust
As luck would have it, an engine builder I know recently built a
Cleveland with the 208cc heads. They use 2.07"/1.65" diameter
intake/exhaust valves.
> CHI dual plane air gap 4150 manifold
Interesting. The CHI website only lists a single plane intake for the
208cc 3V heads. Those have a unique port (designed by Dave Storlien
for his EMC entry, they have the tallest of the CHI ports). In the
past, CHI has provided spacer plates so that 351C-2V intakes (like the
Edelbrock Air Gap 2V) could be used. Then they used Scott Cook's
(non-air gap) dual plane but, AFAIK, Scott no longer provides intakes
to CHI. Your invoice lists a dual plane part number so this may be a
new intake option. When your intake arrives, if you could snap and
forward a few pictures, I'd appreciate it. For now, I'll use the
dimensions for an Edelbrock Air Gap dual plane intake.
> Steel billet flywheel 157 tooth
The Pantera bellhousing and 351C block plate are designed for 164
teeth flywheels. I've used a SBF block plate on a Cleveland and ran
157 teeth flywheels before but there are starter clearance issues with
the stock starter. You can roll the lip of the oil pan for clearance
or use a mini starter.
> I also have a 180 degree exhaust by the Buyers brothers.
I will need the dimensions (primary length and diameter, collector
length and diameter) for these. I have some dimensions for similar
headers I can use, for now.
> Ferrea 6000 swirl polished valves and hydraulic roller springs
I will need to know the seat and open spring loads, along with the
safe lift limit of the springs.
