Does anybody sell a gasket kit for the LM7? I have finally decided its time to put my LM7 back together in preparation to have a running car. Looking around I am having a hard time finding gaskets. I need all the gaskets for the motor, as I, in all my wisdom, threw away the stock, from what I've read reusable, ones. Is the dealer the best place for new ones?
I also need head bolts, main and connecting rod bearings. The bearings were fine, until moving them from place to place too much I ended up putting scratches and gouges in them.
I know the head bolts vary by years, but do the main and connecting rod bearings? When I had the cam bearings installed I know they varied by year. I forgot what year my motor is, which is located 45mins from me. I tell you, I can't win with this thing! Thanks for any advice.

Another question. When I had new cam bearings put in, the machine shop said that there is two different sized cam bearings for the LM7. True? Does anything else change between years? I'm honestly not sure what year my motor is.
The block casting numbers are 12551358 and the head casting numbers are 12561706. With these numbers I can't nail down an exact year. I guess I'm not too worried about the gaskets, I figure those should work out between all years, but I may have to buy new main and rod bearings and want to make sure they'll fit. Any help appreciated, thanks!

the ls1 head gaskets and intake gaskets are differnet but the cover gaskets should be the same.
I was not sure of the year of the block I have I just orderd one set and I did not have any trouble putting it together.. did you ask the guy I posted link to and see what they said?
