Gen II 426 hemi v. gen III

Gen II all the way.  However it must have dual-quad.  EFI or cab, must have two things up on top.

Gen III way too common and unless those valve covers are covered up, they're fugly as heck.

Well I guess this one will be disappointing then bc I am going to run 1 EFI TB on it. I already have the intake and the AC for it.

If running a bigger than factory Cam using OEM or reproduction Hemi Valve Covers:

Spring PSI needs to be increased.

When you order aftermarket valve springs; The circumference of  the valve spring is slightly bigger.

The clearances are so close on OEM exhaust spring outer edge already to valve cover originally.

So what happens is the edge of  the new exhaust spring will begin slowly eating away on the  inside of the valve cover.

Only 2 fixes:

1.Stretch the inside of the valve cover for clearance. Which I ended up doing
2. Know this beforehand and get Bee hive exhaust valve springs.

Hopefully this tip will help you avoid a future headache I previously experienced.

Thanks, I really appreciate the advice and information. I believe I have beehive springs but will have to check.
