difference in rb30 heads?

[88-vl]

just wondering if anyone knows what the difference in the rb30 head is? (as in number wise)
my old head has 672 then 1 under that and the new head has 672 then 3 under that and then L under the 3? does anybody know what this means?

probably just stamped at factory to determine something dont really know...
Turbo head is same as NA head though only the cam is different with the lobes are slightly different to allow more exhaust to turbo and intake etc. 5degrees or something.

ok sweet. do you know if the lifters have to go in a certain way as when i was changing over the cam and rockers a couple of the lifters cameout and i just put them back in there where i thought they might go. they have a little hole in the side of them obviously to let the oil threw but no idea?

[detox_nath83]

anyway as long as u marry up the lifter and the cam lobe it came from dont mix and match , oil hole anyway it can go. clean them and soak them in fresh oil b4 u put them back in...
May wanna hear from other members as well b4 u continue. or have a look around google.

1 means series 1, 3 means series 3.

not much difference except for porting. dunno what the L means.
