For thousand dollars, not much selection, cylinder heads are expensive in these days, you could try either Dart heads or GT40 heads. I would go for Dart heads. unless there is someone out there tells me you can get other brand for thousand dollars.
Alloy trick flows are around $1000.00 I'd go Track heat just to get the better valve gear..Check out what every one else uses on the bottom of threads..Edelbrock/ Holley about the same price..
E,F.R's are good but alittle dearer.. The latter maybe better for you don't need hardened pushrods and roller rockers..
