Well after 500 miles, My veiws and seat of the pants driving,
On the Low dollor parts.
Low 1 - High 10.
Intake - china knockoff Air Gap.
Overall Looks 7
Runners 8
Ports matching gasket 9, very little clean out to do almost perfect match.
Fit 6
Rear machined to thin and has oil leak. Head fit is flat and tight.
Headers - Flowmaster long tube ceramic.
Overall looks 9
flange 7 mid thickness
collectors 5 too thin.
Fit 8 tricky bolting but good fit and room for linkage.
Cam - rv grind no frills.
The lower end tork and mid range Throttle responce Have risen a modest 25%
The miss matched 289 sounds like a 390 Idling at a Stop Light.
Will have a Mileage check as soon as I quit playing.
But It sure makes for a fun driver.
