I have a set of heads that I think I pulled of the LH I had many many years ago. The cast number is 2812174. Are they original LH fitment or later replacement castings?
I will probably look to get them out of the shed to a new home soonish.

I've never seen a 77 casting number on a Holden or Torana before. 7449033 is the casting number for a HT-HG 253 or 308 though, you might have misread a number. These heads are very similar to HQ-HJ, LH-mid LX heads, they just have 1 x accessory mounting boss and hole missing on each end of each head (the top outer-most one).

So to clarify, this means the original fitment heads had a different casting number?
