Hi 830hp.

7449033 are 253/308 V8 heads off an HT or HG. They are virtually the same as normal HQ/HJ/LH heads except they have one less mount lug & hole on the LH front/RH rear face. This means that the HQ/WB style alternator mount won't fit properly.

AFAIK there is no other differences & this lug/hole thing shouldn't be a problem on a Torana with its RH alternator mount.

Dr Terry.

I'd also like to thank Dr. Terry as I have the same heads and was led to believe they were L34. I was going to try and find out one day but you have answered the question for me.
