Paul,
If you can get all the parts, which shouldn't be a problem, there should be no reason why you can't get to the car show. geting all the new parts fitted will take a couple of hours at most.
Regarding whether you have solid lifters or hydraulic, if you have adjusters on your rocker arms, this would "generally" suggest that you have solid lifters, if there are no adjusters, then they are definately hydraulic.
Now go get it done and get to that car show ;-)

Cheers
Paul
