stock heads blown..now what?

[fongo]

What a bummer! After 177K on the odometer and a clean engine (never red-lined or raced!), they tell me at the shop that my cylinder heads are gone (white smoke coming out on exhaust, brown sludge on the oil filter, coolant sipping into engine..ouch).
I need recommendations on a new pair of heads with the following considerations:
1. Low to mid band torque (1500 - 35000 rpm)'
2. 50 state legal (emissions)
3. Quick robust response and durable (not intending to race)
4. Direct bolt on to OEM block (w/ little to no modifications) and stock upper and lower intake.
5. NMT $1400 pair
6. Fully assembled.
I want something I can bolt on myself over the course of a few weekends or perhaps with a buddy.
A friend of mine recommended the Trick Flow or GT40X heads but I'd appreciate any suggestions. Thanks!
