I almost forgot to mention. I'm using a very thin piece of foam for my hood liner and I typically get that suction sound when I pull the hood off. I always have to pull a corner as well as it's tough to pull the entire front up.
Unfortunately, I've done a lot of engine removal from various hulls and my back is not the best. What I've learned is, if I put a little pressure on my back a 3-4 times to warm up just before lifting the engine, my back doesn't hurt the next day. If I then put an ice pad on my back while I hook everything up, I have no back pains afterwards. If I don't do either of those, I can count on my back hurting for at least 2-3 days. Hope that helps...
