cylinder heads indentification

[Jurek]

I have set of new cylinder heads sitting on shelf for about 8 years. My van has 86 6.2 and truck is 97 2500 F 6.5 turbo .I try to find out if they would be good replacement for eigther of my vehicle.The have some # 10137567 and GM-O in the area of valve springs and next to injector hole #567 and L214. Intake valve is about 1.850dia. and exhaust 1.315 dia. precups holes are .680x.380/ are they big or small/ on thy left side of the precup is : on the right T. I have bougth those heads as spare years ago. I thing the are for HD6.2. Not sure. If I need could I use them on my 97 6.5 turbo. I know vans have diffrent angle, but basic questions is, can they be used for eighter 6.2 or 6.5 blocks. Thanks .Jurek

6.2 or 6.5.

Van will have different (older style) injector angle. You'd have to swap lines to use heads, but otherwise everything will bolt right up.

use head gasket that matches cylinder head itself.

The T precup heads are 92-93 6.5 Turbo Heads. will work fine on a 1997 Vin F.
