    No Kody I don't...but I use the ta ones and coat them with spray copper and they are good....so ....you know what they say....if it works ...

    You will have alot of fun when your there.....tuning is half the magic because you will learn all the little fine things you can do for even the littlest gains.

    Why did you coat them in spray copper?

    It helps seal them. I do it with every set of head gaskets I use.

    Ok, new question. How would i find out my cylinder cc and my piston to deck clerance?

    u can take ur heads to a shop and have them cc'd, or buy a kit like from jegs and do it yourself. its not that hard to do. good luck.

    Kody...
    To find the deck clearance you need to have the heads removed and a dial indicator...can help you more if you need....the heads, you need to have them off and upside down with plugs in and a cover( plexi or somethig to act like a block ( know what i mean ? ) and then a measure something from your chemistry class ( thats where i got my first one ) and them measure it as you fill it..

    the shortcut i was talking about is using that CC kit to CC the cylinder with the piston at TDC, then use that number as the piston relief and set the deck height to 0 in the calculator.

    that will trick it into working right :TU:

    only problem is the deck surface of the head needs to be horizontal (parralell to the ground, means out of the car)

    if you buy a cam degree kit (like from summit, maybe kragen) it has a gauge that you can use to measure the deck height, its not as accurate, but it will give you a rough estimate (it wont be too far off).

    plus you can use the kit to degree the cam correctly.

    I got orange crush head gaskets, should i spray the copper onto them?

    Kody...

    Don't be too concerned with the deck clearance because you already have your block and bottom end done......those steel shim gaskets will be like decking anothe .020.
    Once you have your heads off you could check the volume of them and play with that ( remember that you may need adjustable push rods before too long ) but thats really where your going to make the difference.
    If you really want a big change have those heads near 54cc and have them ported .....thats a huge bonus !!
    I have my heads done and it seems like it just wants to keep reving no matter what !!

    i know my dad had some head porting done, but i dont know exactly what.

    I still don't understand. The TA C110 is a bigger cam(At least for advertised Duration) than the 212. The 212 should be better than the 110 for low compression. The 212 gives me a 7.0 DCR with 8.5 SCR. The TA C110 gives 6.8 with the same SCR.:Do No:

    which grind did you use ??...says they grind the 350 cam on a 110 not 112 ...?

    Thanks Mark,
    Just saw that at the bottom of the page. The 212 on the 110 LSA gives 7.1 DCR with 8.5 SCR. The 212 still looks better on a low compression engine.

    probably cause the c110 has 6 degrees less duration at .050 on the exhaust side. im still a little new to the dcr thing larry, took me long enough to learn scr.:Dou:

    Ok guys im gonna start tearin it apart tonight. I wanna get this done as quick as possible, so i dont wanna take off things that dont need to come off. Could someone make me a list of the parts that need to come off to get to the timing chain?

    Kody...

    You first need to empty all the radiator water, remove the dist and water pump, and then the balancer and fuel pump. Next remove the timing cover to expose the chain. I would really rather have the intake off to be more acurate but you could leave it on ( if you are changing to the shim gaskets you will need it off anyways).
    This way with the heads off you can check the deck hieght too and even cc the heads.
    Anyways if you are just going to advance the cam and not degree it then you can leave the intake on and just rotate the sprocket to the correct mark.
    You know what i would do but you can do what ever you think suffice. Start with this and we can get you futher later.....

    Larry I would agree with the 212.....looks like a well thought out cam to me.
    Still think Kody can do well with the 110 if he gets his cylinder pressure up a bit.

    Me too, wonder what his true SCR is

    You know larry...I have to tell the truth as i have not seen 9-1 pistons out there...not there aren't but I would think he is decked they most likely took no more than .01-.015 and the heads no more than the same.
    Bet if he used the shim gaskets he would be close to 9.5 or so.... think ?
