304 5L spark plug gap

[GTP 85]

Hi all... simple question

What have you guys found to be the best spark plug gap for the 304 v8?

Tried a few different gaps and mine seems really sensitive to even the smallest reduction in gap.

at the moment i have them at 1.2mm, seems to run the best

what plugs are you using? ive got mine gapped at 1.3mm in my ute, seems to be happy there

Bump! - Anyone know the gap for the VT, being the same motor, I'd assume it's the same gap ?
Got new plugs to put in (just some NGK R's which I don't believe are anything top of the wozza) just wanna know whether I have to do the gap myself or if they should be okay to plug and play
Hoping to do it today!

Cheers

The NGK BP5FS are the way to go I think they have a 1mm gap which is fine.
Some people run there gap down to .8 and some run 1.2mm iv found it never made a great deal of difference.

Cheers wez,

will just run these plugs for the moment which are the BPR6EF ones I think, figure if my current ones are cactus.. these will be more than a good step up.
Will get better more expensive plugs when I'm chasing much bigger performance.

Sorry the NGK number i said waz for the carby 5L, The ones you have are right but still have the 1mm gap the BP5FS have a 1.5mm (carby) .
Dont fall in the myth of more expensive plugs such as iridium plugs are better for performance they only last longer.
NGK even say this on there web site.

ah well, $5 a plug I'm happy with, beats $20 !

I run 1.1mm, on platinum plugs. I basically run them cause i cant be assed changing plugs every 10k. These ones have done 50k so far and i really dont feel as if they need looking at yet. With ABS its just a pain to to the Driver side.
