I'm looking for a CRG member that lives close to Lawrence KS. Anyone?

  I live right up the road in Leavenworth.   

Inside or outside the prison?

[LVN 67]

If I had a dollar for everyone on those, Id be looking for a 69 COPO or ZL-1 with cash in hand.  Im outside, but Ft Leavenworth did build their new jail right across the street.

LVN 67; I'm interested in a pair of 2.02 fulie heads from Craigslist from a guy in Lawrence and I need someone to be my eyes because I live in Ohio and that's a little far to travel to check them out. Can you help?

[LVN 67]

pjbizjak, Bummer, I 'm leaving for Florida later this afternoon, and will be gone about 2 weeks. If its not too late when I get back, I'll be happy to go look. I'm not much of an engine guy, but I can get some pictures for you.

Is this the ad advertising a set of 291 double hump heads?  If so, it is hard to tell from the photos, see why you would want a set of eyes for a first hand look.  I would say that they need to be cleaned up and magnafluxed to know if they are any good, otherwise you would be taking a chance.  Did notice that they have been modified for guide plates, not completely stock heads.

Just my two cents worth.

[pjbizjak]

Thanks again LVN 67, have a good trip, we'll see when you get back.

1968 z28; The ad was on Graigs list and I got some extra pics he sent me, they look good.

Thanks Pete

Just a heads up...if they have added hardened seats for the exhaust valves, there is a possibility of the seats leaking water.  Sometimes when they grind into the seat area for the hardened exhaust seats they get very close to the water jackets or even break into the water jackets.  That is one reason why I mentioned that they might need to be magnafluxed.  I prefer to start out with a set of virgin, magnafluxed, 1.95 set of heads and have them modified to factory specs for the 2.02 valves.  Cost a little more, but at least you know their good.

I am sure most of you know the score on the heads. How they have a different thickness in certain spots etc. But here is a little comparison for fun.

[dannystarr]

Here is a couple more shots of original heads. NOT 194's that have been punched up.

[1968 Z28]

Danny....You are so right.....good call.  Many of the 1.94 to 2.02 modded heads don't include the intake valve radius cuts to open up the area between the intake valve and the cylinder wall.  This radius cut accounts for the thinner area between the two adjacent intake valves.  If this mod is not done then the modded heads will flow less air than the original 1.94 heads.

I have a set of 291 heads that I had modified from 1.94 to 2.02 valves recently and I made it a point to get the machinist to open up the intake valve area. 

I went back and looked at the photos of the heads I was referring to in the Craiglist ad above and it appears to me that the intakes have not been opened up.  All the spacing's between the cylinders look the same.

[pjbizjak]

Dannystar; If I send you a picture clould you tell me if the heads are original 2.02's. I would need your email address.

I can give it a shot. There is much more knowledgable guys on this site than I. William, JohnZ, Jerry M, Paul, and the list goes on and on. Problem is, ya gotta be able to see if they have been cut. Ya need to see the difference in the casting. When you cut a 194 head, even if you relieve the correct area's, the casting from the cut shows differently. It's not as smooth in that transition area. But sometimes, TOO smooth. I hate it when they do that. I understand the reasons, they want the stronger thicker casting. PM me and I'll take a look. Here is the kinda shots I need... Danny
