A5202/5216 lobe on a 108 lsa
That's a .480 and a .490 lift

A 5006 intake a 5136a lobes on a 108 also
That's .486/.514


5443 intake is .485
544 intake is a .509
5445 exhaust is .520
5435 is .485

And that's just flipping through a few pages.

You use the vale lifts the help determine how fast the ramp is
Some motors like using slower ramp speeds like the late model hemi

If I had it ground I would run it as a 5443/5445 108 lsa and if she is a real low compression motor dana few degrees advance.

Other wise leaving it straight up is fine.

The napa branded octane boosters work rather well at that too.
We use them in some stock Harley's on real hot days. Works well.
