Comp 26120 valve springs on Champ Irons?

[Lil Truck]

Has anyone used these springs on Champion Irons?

Considering them for
T&D 1.65 roller rockers
206/210 Roller cam with lift @ .550 with 1.65 ratio
Morel Hyd roller lifters

Installed height 1.880 @ 155 lbs
Open 1.280 @ 377
OD 1.445


Thanks

Theres no easy way to get that spring on an iron head. I ran them at .040" from theoretical coil bind with a 218/224 xer cam and it revved to 6000 rpm and made 700whp with the turbo out of breath on aluminum heads. I did run 1.65 rockers and had 885 lifters. Pac 1201 can be used in the same application and fits with no special mods

Thanks Brian,

I saw you had used them, but the post did not say iron or alum heads.

The 1201 with a plus .050 lock should get you 1.750 installed height which will put you right where you want to be. Make sure you check the installed height of spring.

Thanks Mike,

I was concerned with coil bind @ .550 lift and the 1201?

I am sure you have insight on this.

.550 is the limit if they go in at 1.750, this leaves room so you will be fine.

At 1.750 installed height and coil bind at 1.115 equals to .085 from bind with a .550 cam so you are good
