klze/klde valve train specs

[babyblueMX3]

hey guys..I know this could be usefull..Me and skelly on probetalk are completing a full analysis of the ZE heads..I added pics of all the components...this IMO should be stickied or put in the FAQ..here it goes

from skelly:

Okay, here we go. Most measurements are rounded off to the nearest 0.005" because of observed difference between same parts as well as inconsistencies in surface textures resulting in variable readings. I don't have any reference as to OEM specifications, but I expect you'll find these to be pretty darn close except in the case of the inadvertent type-o:

intake - exhaust - measurement

1.705 - 1.830 - valve spring uncompressed height
1.160 - 1.045 - valve spring O.D.
0.800 - 0.750 - valve spring I.D.

0.230 - 0.230 - valve stem dia.
0.175 - 0.175 - valve stem dia. @ clip (jargon?)
1.258 - 1.085 - valve face O.D.
3.745 - 3.745 - valve overall len.

1.110 - 1.000 - spring seat/shim O.D. (jargon?)
0.610 - 0.700 - spring seat/shim I.D.
0.018 - 0.018 - spring seat/shim thickness

0.350 - 0.350 - spring retainer lower I.D. (Note 1)
0.390 - 0.390 - spring retainer upper I.D.
1.113 - 0.985 - spring retainer O.D.
0.320 - 0.335 - spring retainer overall height

1.295 - 1.180 - Lifter O.D.
1.235 - 1.115 - Lifter O.D. @ oiler (Note 2)
1.215 - 1.100 - Lifter I.D.
0.400 - 0.400 - Lifter center pin contact surface O.D.
1.025 - 0.945 - Lifter overall height

Notes:
1. The retainer's I.D. is tapered to use spring pressure to increase pressure on the clips
2. The lifter has a groove in the outer edge. This is the diameter of this recessed groove.

I took some other measurements today..

ze intake ports:
1.85x1.15
corner seems like a 0.35 radius

ze exhaust ports:
1.65x1.02
corner seems like a 0.50 radius

97 a-spec millenia intake manifold ports:
1.81x1.10 (they seems a LITTLE smaller than the ze head intake ports)
66mm neck(parts that meets the TB)

some k8 measurements..

k8 exhaust manifold ports:
1.81x1.21

downpipe:
1.78ID(part that connects to the exhaust manifold)
1.90ID(part that connects to the cat)

kl01 vaf is 60mm


these measurements would be good infos for someone trying to do a port and polish or portmatch anything

[mdavis]

This is awesome info man. Imma be tearing my motor apart in spring to port/rebuid and this is going to help a lot! Babyblue is going down in MX-3 history!

Are the curved neck ZE motors the same as the millenia or the same as the all other ZE's?

[babyblueMX3]

both have the same heads so I assume they are all the same.. the measurments I took though came from a ms8 ze (straight neck/kl31 cams)

[bubbaflaat]

VERY nice, very very good information to have. I'm truely impressed Babyblue!! Good work man! And skelly on PT, isn't he the one who fabricated the MAF coversion for his probe? He is a wizard too!
