V8 rockers on 6 cylinder ?

Has anyone fitted V8 non adjustable rockers on a 6 non adjustable head ? Went to a wrecker to check them out and he said it wouldnt work, said the pushrod to pivot piont is where is needs to be different[?].. The differance I could see was the [V8] hole where pivots from was in a different spot and the length too the valve stem was longer.I was just going to try it to see if it gave more lift to the cam, see if my motor can take a bigger cam ?
Cheers, Rob.

If you don't mind wating a couple of days, I could check this out..I have a large supply of 6cyl. heads in the shed.
You CAN fit longer rockers to an ADJUSTABLE head..I have done this myself.I used a F#@d rocker, with a little grinding at the valve end, this was to stop the sides of the rocket contacting the valve spring retainer.
I have used std. rockers on a cam with a bit more lift, all I did then was use the die-grinder & make the slot in the rocker (where it pivots) longer.
Also, an old speedway trick was to fit longer rockers to the exhaust valves only.
Q-ball.

you could make them fit, but it would be a bit of a nightmare.

six cyl rocker ratio is 1.5:1, installed height of around 1.625"

V8 rocker ratio is 1.65:1, installed height of around 1.700"

depending on which rockers you have in mind, will the installed height be an issue. (twin shaft pedestal type). watch out for spring bind.

you can run SBC rockers without too much modification. head needs rocker bosses drilled, tapped and machined to suit studs. wont be a cheap process though.

nobody.

posted this reply to the other question the other day:

yes it works, wont be the best long term as far as valve guide wear goes but it could work well as a test for you to see if you need more cam.

some sneaky cheatin' hq racers have been doing it for years...
