i just realized world product makes 2 different s/r torquer 305 heads, hydraulic flat tappet setup or hydraulic roller, i had these heads from a previous build, they are on a hydraulic roller motor now and i found a cracked intake valve spring...

world states 1.250 dia springs 100lbs @1.810 max .500 lift

the roller heads have 1.440 dia 125lbs max .600 lift

i'm using a crane 2032 roller with 1.6 rockers .482/.496

the cam car says to use crane 96802 springs.

would these work in the heads as they are bigger?

 

You should be running the larger springs.

AFAIK the head casting is the same; it's just a question of which hardware they're equipped with from the factory. You can put either kind on them.

 

thanks bud, i contacted the support, that's what he recommended.

another question, i'm looking at the heads and it looks like the spring seat is just large enough for the existing 1.250" springs, does that mean i have to pull the heads and have them cut bigger?
