Welcome to AF.
I am not sure if you intend that comment as a joke, but please be a bit more gracious and appreciative to those people who are volunteering their time to help you.

If you looked the engine up on-line, http://en.wikipedia.org/wiki/4A-FE
you would know that the 4A-F and 4A-FE versions were virtually identical except for the fuel delivery system. This means the reciprocating assembly was virtually the same and the redline recommendation made by drdisque is valid (and is confirmed in Wikipedia).

IMHO I think revving a 20 year old engine to redline is asking for trouble.
Also, 6300 rpm is well past the 4800 rpm torque peak. You will go faster if you shift before 6300 rpm.

I shudder at the thought of getting info from wiki.
By its very nature it is unreliable, and the huge variety in Toyota engine designs means it can never be truly accurate.


That said, somewhere between 6,000 and 6,500rpm is a safe redline for these motors.
Be aware that at anything above 7,500 they start to throw bits of the valve gear out of the rocker cover.

.

Imho Wikipedia is a good starting point, especially for the basic concepts that this member is looking for.
I quickly read through that article before posting. It was brief and vague but I did not see anything obviously inaccurate , (althought the SAE folks may take issue with it. )
