Default Cylinder head questions.

Any guidance would be appreciated. Search is down, so I cant find my info.
Question 1. Is mainly for the C4 folk. I have 1.6 Summit RR's. Is it at all possible to use the stock size valve covers? If not are there any recommendations as to what would fit. It looks like it is quite tight on the drivers side. I like the Edelbrocks, but they say that they are 2" above stock height.
Question 2. If I remember correctly we DO NOT have the self aligning heads correct (1985 model year)?
Question 3. If we do have self aligning heads the guide plates are not nessessary, correct? Or are they mandiatory with RR's?

Sorry if these questions sound to common( I knew this crap 15 years ago). I wasa working on the car & my back went out again, so i'm hoped up on my meds.
The reason I asked these stupid questions is because I have the pressed in studs & after al the s**t I went through with this motor( see previous posts). I really REALLY do not want to rip the heads off of it.

Any help qould be apprecated.

1.) The rockers should clear the stock valve covers by shortening or removing the drip tabs, inside the valve covers. You may need narrow bidy rockers to clear the center bolt towers.

2.) The '85 HEADS are self aligning, and therefore don't use guide plates or self aligning rocker arms. Never use more than one method of alignment on any engine.

3.) The push rod is guided by the slot in the head that it passes through. With 1.6 rockers, there is a good chance that the push rod will rub at the top end of that slot. You can elongate the slot with a Dremmel tool.

Even with stock valve springs (you didn't mention them) the 1.6 rocker MAY play havoc with those press in studs.

RACE ON!!!

CFI-EFI, thanks for your respectful IM. But, let's not be fooled. Just look at my sig pic and you will know who is the original Wheelsup.
I wonder just how many other ways there are to try and confuse who's who. Hmmm. how about wheelz up or wheels upp.

Thank you.

wheelsup. I didnt know about your name or wouldnt have registered under it( will change it if it means that much to you. It is after all a SCREEN name).
As for being original( how many people have this name. Atleast 2 on every board...LOL). I've had it for about 12 years now. Since my first wheel stand in my 78 camaro back in 1993.

I highly doubt you are the original wheelsup, as I know I am not either..

Thank you for clearing that up CFI-EFI. I was quite out of it with all my meds so I couldnt think straight.

You have missed the main point that I was trying to make. It's the potential confusion that this can cause. No offense intended, but I do not want anyone to think that I'm you or that you are me. I'm sure that you feel the same way.
BTW, I'm not suggesting or have I suggested that you change your CF name. Like you said, when you registered you did not know. I'm just letting you know that someone else had already (2000) registered the name Wheelsup.

wheelsup, thats cool. Sorry, if I sounded harsh. It wasnt intentional. I was quite loaded with meds the last few days. But now, after going to the Dr & finding out my back is in VERY bad shape( they say I should really walk with crutches now). I decided to get a little drunk.
I would gladly change to WhEeLz Up..LOL Considering both projects have been on jackstands for a little over a year & the wheels are literally up.

ANYWAY, as I was looking back on this thread, I coudnt belive I asked those questions.
I must make a few corrections though. The 1985 heads ARE NOT self aligning. The self aligning heads didnt appear until 1987( center bolt valve covers) & using NON self aligning RR's & guide plates ar eth eway to go. It goes the same way for self aligning. You do not use NON self aligning RR's on those.
So for PRE 1987 it is NON self aligning & for POST 1986( 1987 & later) you use SELF aligning.

CFI-EFI, The heads are self aligning. Meaning they use a NON self aligning valve train. But they consider them NON self aligning heads.


Now, that i'm a bit buzzed & just talked to my old friend I used to build motors with. It's all coming back to me. Working on these foregin cars for the last 9 years, has really messed up my mind.

Evidentially! Although, "self aligning" heads is not a common term, that is exactly what they are. With the cast iron (624) heads, there is a slot that the push rods pass through that keeps the push rod from wandering from side to side. THIS keeps the rocker arms aligned with the valve stems in a manner similar to what guide plates do. Therefore the HEADS are self aligning. NOT the rocker arms...The HEADS. Get it?

RACE ON!!!
