The following is a quote from a post by moderator "Paul Bell".....

--------------------------------------------------------------------------------

LT1 steam pipe behind heads (93-94) (includes bolts, seals, hose to radiator) = 10108635

LT1 steam pipe behind heads (95-97) (includes bolts and seals) = 12556260



My question is this, do the pipes differ in part number due to differences in design? If so, is this difference due to model year differences with the car, or head casting differences?

Thanks in advance.

It has nothing to do with the heads, but with the description you have already quoted. The early one has a hose to the radiator because the water pump and heater hose configuration is different between those years. Look at the hose diagrams on my website.

Thanks, "shbox".

I'm looking at a pair of heads to replace my OE heads which have a couple of damaged threaded holes. The ones I'm looking at, are not the same casting numbers as the ones currently on the car. I recently saw a picture of two different heads, and it's hard to judge from just a picture, but the size of the holes for the banjo bolts appeared different.

I've never heard of or seen of any difference with the holes. If you can get the holes plugged up, you could always turn the heads around and use them on the opposite side they were on and open up the plugs on the other end.
