Selling top end package for LT1

I will be selling a complete top end package for a LT1.
What I am selling is this:
1 competition cams cam part number 07-500-08 gross valve lift .480 .488 duration .060 tappet lift 258 264 with lobe separation 112.
2 aluminum Lt1 heads that have been ported looks to be ported to match the gaskets ,should be an increase in hp due to what has been done to them.( 1.94 intake exhaust 1.55 on the valves)
16 or a full set of rocker arms competition cams part number 1418-16 (1.6 rockers self aligning).
2 sets of springs for the heads one set that is already on the heads and another aftermarket set of springs ( either from the LT4 hot cams use or what is on the tirck flow heads I just purchased)will come with the spring retainers and locks.
1 set of push rods (stock) that has less then 14,000 miles on them.
Everything is brand new except the heads (ported from an existing set) and the push rods (very low mileage) beside that everything is all new. The only thing you may have to do depending on the year of your engine is the pin on the cam which is setup for pre 94 LT1 (shorter pin) you may have to get a new pin pressed into it.
One package for *** which will include shipping for everything and insurance for the shipping, otherwise will be placing these items on ebay for *** min.
Contact me by pm and let me know if your interested.
Should produce at least 400hp at the flywheel is my guess, mind you after doing alot of research this is only a guess but I believe a good guess on the hp produce with this package, I would recommend going with a 52mm TB with it and believe the stock injectors should be plenty with this setup, also would suggest a dyno tune with it as well for peak performance.
