LS6 top end on LS1, pushrod length?
I have an opportunity to pick up a set of complete 243's, the cam and pushrods from a 2002 Z06 for a pretty sweet price. Obviously the heads & cam would be a nice upgrade for my stock LS1 w/853's but will I need to purchase different pushrods? I understand the base circle of the cam is smaller but I'm assuming (you know what happens here) the LS6 pushrod length will compensate. I'm also assuming these heads have the sodium filled valves since they're 02's.
Please correct me if I'm wrong.

I'd think if all the parts from the cam to the heads are off the LS6, it should all bolt on with no issues as long as the head gaskets are the same too. Still would recommend checking the pushrod length to be sure.

They are the same, No difference in pushrod or dimensions outer or inner (for all intensive purposes) you can use your stock GM pushrods. The base circle will only be different if you have had the cam reground in which case I would not be installing it anyways.

basically what everyone has already said lol. if you get the heads and cam the pushrods will be the same. the ls6 cam has a smaller base circle however the ls6 valves are .025 taller than the standard ls1 valves so basically if you get ls6 heads and valves then you are good with the stock pr's. if you get an ls6 came with standard 243's and regular valves you will need 7.425 pushrods
