    Hey ratsun I have an issue with the installation of my cam and cam towers. I used the original cam and cam tower of the U67 head but when I put in the cam and tighten the cam towers the cam doesn't spin at all. I was wondering of I can use the cam and cam tower of my a87 head.? Are the cams and cam towers the same for both the a87 and U67 head?

    UPDATE: okay so I received the head today from the shop and it looks great. Tom milled 24 thousands of an inch which is close enough for me. He did mention the bigger lash caps but quickly stated they'll be hard to find. But that I should be fine with the ones I have.. I plan to clean up the cams, and arms tomorrow and re-install them. Though one torque spec I couldnt find was the cam towers... What is it?

    So its currantly 2a.m where I'm at and I'm excited for tomorrow. I will get my U67 head from the shop milled 25 thousands of an inch. The shop guy (tom) mentioned that my cam might get some time advanced because the cam will seat lower/closer to the crankshaft. TOM, being a Datsun 510 racer himself back the days, suggested I get camshaft shims the raise the cam .020 higher to reduce the chances of time advancement. Which I will get and have located a shop who has them. Though one thing I did do is remove the camshaft and rocker arms myself so that tom wouldnt charge me extra. I'm here thinking of how ill install everything tomorrow and am worried that I will have trouble putting the cam back together properly. I'm worried that the rocker arms well have to much tension on the valve springs and not let me tighten the cam down the spec. Is there a propper way to install a camshaft and rocker arms with the valve springs still on the head?

    Ahhh okay totally see the difference. Thank you guys so much for the info. I wouldn't of been able to do this myself. I would like the peanut head the shop is offering me but I don't think its with the investment on a L16. The L20 is a different story. Question at the junk today I saw a couple Nissan trucks w/ 2.4 liter engines and almost looked like a L series but the intake manifold was on opposite sides of the head. Is this motor the Zblock?

    I checked the head and it has A LOT of meat :D (like the w53 head) Question: how do know if its a closed or open chamber head just by looking at them ?

    Okay let me clear up that my original head was a "A87" it didn't say 210 on it. Though idk if this matters or if its all the same thing. And wow a U67 head dropps my compression substantialy. Makes me regret buying it I actually wanted a head that would help me gain power not loos it :/ but its okay ill make the best out of it. I'll be taking the head tomorrow to get checked and resurfaced. I'll tell the shop guy the mill it down 1mm. Right? Mhmm your right. It might be advanced but ill see what happens when its all put together. Damn ill look into it.

    I went ahead and bought a U67 head off of a 1976 620 w/ a L20b. I see you noted that ill need to "mill" it 1mm. By that do you mean resurface the head 1mm. And will I be able to use my L16 chain with the U67 head w/o chain slack ?

    So I came to my local junk yard and actually found a 620. It's has a l20b in it with a U67 head. I was going to buy the whole motor but it has water in cylinder #1. So I decided to just buy the head for 76$. Is this head a good ordeal or no?
