Re: best heads
Renagade Racing Ported NPI (stock) heads from a '95-'00 4.6/5.4L, w/"PI" cams. Should be more than enough to destroy your trans.

Re: best heads
What he was saying is a set of 95-2000 model heads (Non Police interceptor) ported and modified by renegade racing, with the police interceptor cams installed.
Yes a higher lift and duration cam will make a huge difference, especially with the porting modification to support it.
