seems a pretty stout combo to me, although for my $, I believe you can find a better heads, cam, intake combo.

I paid $935 for TFS heads
$350 for the edelbrock performer RPM duplicate (knockoff, new price)
$269 for anderson ford N-41 cam
$75 for custom hardened pushrods
That's under $1700 with shipping. If I'm not mistaken best price you'll find on Holley systemax EFI combo is $2000 or so from summit.

For certain combos, that Holley Intake ($500 seperately) is the best intake available, box-stock for an EFI car.
I went with performer RPM for 2 reasons:
1) saved $250
2) the holley systemax lower is roughly a felpro 1262 in height, and a felpro 1250 in width. I don't feel like porting my heads at this point to match. (lower will be roughly 0.1" bigger net than a stockers heads).

by the way, you won't have the problem of #2 with the holley heads. their head/intake combo is a perfect match.

other perfectly valid combos are

AFR 165 $1200 'group purchase' price ($1300 normally)
custom cam $250-$300
holley intake $500

so the AFR combo is a little more pricey, but can really make great power as well.

early gen. holley heads were known for some kind of machining/valvetrain geometry problem. Eventually, I believe it loaded valve guides and caused the motor to burn oil. I'm sure on the burn oil part, not so sure on the cause.

early TFS heads had problems, as I'm sure AFR's did at one point as well.
