I need the front and rear metal steam lines with mounting bolts also,i am being told block offs are not too good due to steam pockets.

for a lt1, you only need 1 steam pipe. Its all one pipe that flows from both heads towards the front.

Rear block off are perfectly fine, GM puts them on every engine they warranty for 100k miles, for about 10 years now. The fronts are the ones that matter.

I do have a set of the F-body 4 corner crossovers though if you really want them.
