    The differences between 4032 and 2618 listed earlier in this thread are pretty spot on. I've seen both 4032 and 2618 stuff hold up just fine at higher horsepower levels and bigger boost.... and at the same time I've seen them both fail into a melted pool of aluminum at much lower power levels...

    Caveat Emptor.... Livernois Heads (Pic heavy)

    As you know I'm sorry to hear that you have had problems with the heads and that your experience has not been a good one. Honestly an apology from me probably does not mean much though, I'm new to this situation and have only been working with you a short time now. I'm not really that familiar...

    Caveat Emptor.... Livernois Heads (Pic heavy)

    Missed this when just reading through. I'll try and answer. The original port CNC is setup against the stock manifold. I don't have a lot of info or feedback on the cylinder heads myself as I tend to just be involved with engine stuff. So I asked some of the sales guys if they had heard...

    Sorry, have not been on in a couple of days. Been working in the back and not had computer time as such. Guess I have not been on LinkedIn in a couple of years. That statement was true a couple of years ago, I did used to oversee all of those departments. But things have changed a lot since...

    Yeah, by custom I meant based on my experience from doing my own projects, which were often custom and required non-standard parts. That's the only reason I know of finding those alternative o-rings sources, I needed them for a project. In regards to your heads I have not had a chance to...

    It's fairly application specific, you can make cast iron (powdered guides) work just fine in a lot of applications with attention to the setup, machine work, seals, etc. The same can be said for bronze guides as well, with the correct setup they can be made to last also and work well in...

    Definitely a small area to work with. Increasing the bolt torque will probably provide little to any additional clamping force because the bolt is just stretching most likely at that end of the torque spectrum. In most cases the manifolds are designed to compress the o-rings completely as well...

    I would think that this offer still stands, though I'm not really in the loop often on these dealings. If you have heads that need repair then I would definitely say we want to work with you to try and fix them. Is this something you were speaking with Dave on? I would be glad to talk to him and...

    Caveat Emptor.... Livernois Heads (Pic heavy)

    Interesting, guess the info I was going off was wrong. Well that makes for an odd scenario. Out of curiosity do you happen to know what the lash was set at? The adjustment is controlled in the valve tip height or lash adjuster if an adjustment needs to be made. Curious where it fell, I don't...

    Caveat Emptor.... Livernois Heads (Pic heavy)

    I was asked to have a look at this and see if I could offer any information. Read through the thread and issues with the head. I'm not normally very involved with cylinder head matters so I'm not really too abreast of this situation but I did try and get some info and get filled in. I spoke...

    Comp Cams Adjustable cam gears

    Ahh... yes, if it's more than just a dot-to-dot swap than you will need to remove the cover to get to the lower gear for degreeing purposes. Good catch.

    Comp Cams Adjustable cam gears

    You don't need to take the front cover off to change camshafts in a modular. Just the valve covers can come off if you use a "wedge" tool. The tool goes down in the front cover between the timing chains and is tapped into place wedging out the chain adjuster and locking them into place. This...

    Comp Cams Adjustable cam gears

    Have not seen the current versions of these gears first hand in a while but years ago there was a rash of these kinds of gears failing. They were either cracking through the aluminum plate and self-destructing or the small little bolts were eventually allowing the cam-plate to move and the...

    Knocking near cam phaser help

    From a mechanical standpoint there really should not be any possible issues that can arise from losing the electronic portion of the VCT when the cam phaser is mechanically locked. There really should not be any effect. Was there any other damage to the front of the engine?
