Header question

Well I wasn't able to find any info on the exhaust logs so I have just ordered the Schumacher complete kit with the 4-2-1 extractors so at least I will know they fit.
Is anyone able to run the numbers on these exhaust manifolds? They were part numbers - LH 4041467 (definitely a no. 6 not 8 ) & RH 4047472-2. They may also go up for sale if anyone is interested (shipping from Perth W.A.).
