hi there, i'm going to get rid of some of my excess holden stuff, but don't know what to hold on to and what to sell

the bits i have are listed below and i'd like some advice on whether to keep or sell them please (all are matched pairs and complete with valves, springs and keepers)

casting no.
2812174 on an HQ 253 engine atm (originaly came with my ute)
9947423 from a WB 308,small valves,square shape crossover
9936122 from an HZ 308 i bought,large valves,'U' shape crossover
9947423 from a VK (i think) small valves,square crossover
2812174 from an HQ 308,big valves,no crossover
7449033 from an HT/HG 308,small valves,no crossover

and last but not least, my 'B' cast BROCKIES, currently on my 308 HQ ute, don't know valve sizes

i already have an idea of the desireability of the 'B' casts, but not a clue on the others

thanks in advance, johnny

i hope it doesn't look like i'm doing a sneaky and trying to sell them here where there's more views than f/s. i really just want to find out which to keep and which to sell

but if and when i've decided, i'll put them in the correct forum

cheers, johnny
