friend is getting rid of his 1.8 yella terra's for $300 bc he has to get 1.7 for his new cam. is it worth me installing this a my car that has 130,000 miles and only has lt headers, intake and tune. not going to have cam or heads. if i do go with this what should i expect. also should i buy anything else? am i going to need new shims? i really know nothing about this if you can fill me in. thanks ahead of time.

They'll bump your stock cam lift ~.030 to ~.525, which means you'll need a new set of springs too. So, plan another $75 for LS6 springs. Horsepower gains will probably be in the range of 10~15 at the tire. And, you may need to revisit your tuner - especially if he had you dialed in at a 13.0:1 AFR because it'll most likely lean you out up top a bit.

z06 push rods may be too long as the z06 cam had a smaller base circle.
I am happy w/ my 1.8's, and the tuner couldn't get anything else out of it, my stock computer compensated for this just fine. The a/f was a little lean, 12.9, thats not enough for me to loose sleep.
good luck
