I don't think you can accurately see the difference in height with the photo; The smaller intake is missing it's throttle body.

As far as i know the runners are electronically vacuum controlled, Ill see if i can get a better comparative picture tomorrow.

This could be possible, it is a single cam but there should be adjustable timing gear i can use from a mustang application.

The key with headers for a build like this is they must meet certain criteria: equal length primaries, clean merge, long primaries, primaries not too big. If the primaries are too big and/or too short, they won't build as much low end.

One of the upgrades ford guys say is upgrading the older first gen modulars with the second gen pi heads. The second gen heads have a slightly smaller cc combustion chamber and the pistons where slightly larger cc. With the head swap and no other mods the compression rises from 9.7:1 to 10.3:1. How high of compression could i go before needing to upgrade from regular to premium octane?
this is from a ford performance website:
" Ford Motorsport makes a very nice set of headers for the 96 - 98 Mustang GT. They use a high tech coating to keep them from rusting and ensure long life. Their primary tubes are 1 5/8" and they offer a noticeable gain.
The most important thing to remember when choosing a high flow H-Pipe and catalytic converters is that the 2V engine is very sensitive and easily looses torque if the exhaust is too large. We recommend a 2 1/4" h-pipe, any larger and low end torque suffers significantly. And low end torque is what this engines needs improved the most. The Motorsport headers and a good h-pipe are worth approximately 25 hp."
I did some searching and no one states exactly what or if an appropriate lenght for headers is possible. Is there a math related equation some one knows of to calculate this?
