NO COMPRESSION....wtf?????
I would bet anything that the valves are just not closing. Even if the rings are completely shot you are going to have some compression if the valve train is even close to correct. Need to take a cold shower and just do it by the numbers. The cam is either right or wrong and it is a little concerning to "try it" 180 out. Dots either line up or they don't. I get compression out of the spark plug holes just turning it by hand to adjust valves. I have 30 yrs experience but cant get my adult kid to stop using a hammer and pliers. Not saying that is you..... but if it is all done by the numbers there is no guessing if it will work. Try.... leaving the rockers somewhat loose (after the cam timing issue is resolved). Crank the motor (DON'T START) and I bet miracles happen.

Laser, thanks for the tips, we did try to losten the rockers a little, and still nothing. This weekend I am going to pull it all apart again, take the front cover off and see exactly where the cam is. Thing is that I KNOW its in there right....all lined up etc.....but I am going to try that. The last thing is to pull the motor again. I am also going to try the oil on the pistons, and maybe that will do some good. As for the valves, well they are fine. Not a thing wrong with them. He went over the heads with me and Eddie standing there. Pulled the valves and checked them, put them in some sort of machine that spins them around, and they were straighter than my pecker
He even checked the deck height on the heads, still stock, well stock size, since they are Absolute Stage II's. So hopefully I can figure something out this weekend, and have it fired up by Sunday...we'll see. I will keep you all posted on my progress. And thank you all for your help, I really appreciate it.
Oh, also, some else I talked to said that the rings still should be good, no matter how long the block sat, but I just may need to throw a little oil in there to get them to seal correctly. So we'll see how that goes. Still waiting for my studs to get here(hopefully tomorrow). Thanks again

when you tighten down the rockers, tighten to zero lash (where the pushrods dont spin) then turn another 1/2 turn. i think Ivy is gonna send out your heads as soon as she gets to the store to get wrap for them.

You have to admit, so far this job has not gone too well. I just assumed from all the issues you have hd so far that you had never done any thing like this before...
Sorry...! ...just trying to give some good advice..... ...so keep going and think things out carefully before proceeding - if you have a kowledgable freind friend - use him.

The search button tells all...
I understand this issue has been pain in the *** and you just want to get it running at this point, but if the heads come back off again it is imperative that you take the time to make sure everything in there is super duper clean. I would limit the oil to the cylinder walls (to oil the rings) to using WD40 and vacuum (shop vac /small nozzle) it out where it puddles up in the corner a few times. Then a light wipe on the walls with 30 weight. Whether there might be dirt in there wont be in the back of your mind after that.

Im as frustrated as all with this car and ive never even seen it only taken Rob's calls to help him diagnose. I havent touched the car so i dont know if what Rob is saying is whats really going on. I didnt have the time to go look at the car when he had it here in Dallas visiting.

Hey: Just trying to help you out I know how frustrating it can be. I think your head gaskets were not seating right and that is the reason you had no compression. You had a shop check the heads I assume they checked the surface to make sure they were straight. Before you do any installing check the block deck with a metal ruler and a feeler gauge. If you can see daylight through it the block deck will have to be machined for sure. Check the specs in the book for acceptable warpage. Clean the cylinder bolt holes out with compressed air. The head bolts you used the first time may not have seated all the way or they may have been to long? I would use new head gaskets. Borrow a degree wheel and make sure the cam is in right. As others have said bring each cylinder up to TDC with the valves closed and do a leakdown test before trying to start it up. Another stupid thong to check is the spark plugs. Are they the correct plugs for the motor and are they tightened down? Seen it before the wrong plugs in a motor and the compression just leaked out of the hole. Hope this helps? Bye

Thanks for your input Stick....as for the plugs, yes brand new. We had spark as well as fuel. The block is pretty much brand new. Came out of an 02 vette with under 5k on it. When I picked the block up, I took the stock heads off of it. And the factory gaskets. The guy who checked out my heads, looked them over thoroughly(sp). The first time I put it all back together, I used factory head bolts (this time I am using studs). I did double check the head gaskets when I pulled the heads again, and they were on right the first time. Again, thanks for your input. I will keep you all posted this weekend......
