can the 86 GLHS head used on a t2 block?

silly question, but does it have to be a cross drilled in order to avoid problems? thanks, chris

It will work fine as long as you have the correct gasket. Do not use the MP 2006 gasket, but rather the MP 2005 or equal. Look for a keyhole type slot where the crossdrilled holes should be.

does the t2 block utitlize the common block crankshaft or t1 crankshaft? thanks for the reply..chris

All true T2 blocks used the heavy, heavy duty forged one. They all use the 8 bolt flywheel pattern.

The early TII block used an early TII forged crank. The CB forged crank is specific to CB engines. They do not interchange between the blocks.

What the diff. between early and CB T2 cranks anyway?

The TII non common block crank will fit in a common block however will NOT work becuz of the seal retainer (crank gear side ).. You cannot use a common block seal retainer for a non common block crank/ or vise versa. ( The screws do not line up + the dia. of the seals are diff size ). You cannot turn the Dia. down either to fit ( on non Cb crank to fit the common block seal retainer ) cuz the seal will not reach it to seal anyways. I have pics of all this if someone needs to see for proof..

The main caps are 1/4 thicker at the screw areas on a CB therefore using a 1/4 longer screw aswell.. id imagine these can interchange. but just noting the diff.

The crank gears are different aswell and cannot be interchanged ( square tooth / round tooth )..

so i need the crank and cam gears and mp headgastet 2006? anything else...

Sorry to hijack, but just to clarify, so the 2006 has the slots for the crossdrill colling and the 2005 does not? If using a non drilled head and a drilled block or vica versa, wouldnt it be better to use the 2005 without the extra holes? I"ll be in the same boat as cjo11 this winter.

Yep, You would both need the 2005 gasket. The 2006 gasket is for crossdrilled head and crank.
