230 Rebuild? Is this normal???

[chevylookin]

Hey guys, recently had my 230 rebuilt. First off, Im not a performance engine know it all by any means and just wanted to keep my little 230 for gas efficiency in mind but I had built up a lil. I had a 272 cam installed, lumped the heads, bored it .30 over and installed roller rockers. I gave it to the engine rebuilder and when I got it home and took the plastic off to install the oil pump and covers and what not, I found that the two valves that where under compression looked a little strange. The two lifters under compression are sticking almost 1/2 an inch out of their bores. (hydraulic cam I am almost 99% sure) I just gave these specs to the engine rebuilder and gave him gobbles of money and let him do the work, and presto! I expect a perfectly rebuilt engine back, right? Is this normal??? Are the lifters suppose to move up and down out of their bores like this??
