I have never used one of these , I have used the Eddy RPM , Eddys use a soft alum & are made in China & have poor port alignment , not high Quality so possibly this is actually made from better material or at least equal , could be the casting is more accurate also .
If your heads have not been...
If you have any room above the trans you can put shims in the rear trans mount ,
Less desirable is raise the front of the car using the T bars , make sure the car is lifted before trying to adjust it !
There is a lot to this , seriously your Best cooling by far is a 5 or 7 blade clutch fan with a shroud , no electric fan comes close .
ELectric fans never move as much air as a clutch fan but also do not compensate on the highway & can block natural air flow .
second Alum rads must be...
Many systems eliminate the tapered roller brgs & force the use of green brgs which is a Huge NO for me , they can interfere with the rear sway bar in many cases And as above are not really warranted unless you are on the brakes hard a lot such as autocross .
The first place I would look is...
A good 5 or 7 blade clutch fan & shroud is more effective than an electric fan set up if it runs hot in traffic you need more airflow , on the highway the fan can block airflow , 180* or 195* T stat is a must .
Fuel mix & timing can also affect heat , richer mix & advanced timing run cooler ...
