Ecotec stem seals on Buick

[Yankus]

Hi All,

I have some MACE 1.9:1 rockers on the way and was thinking I should do the stem seals and retainers at the same time.

Question 1: Will ecotec stem seals (low-profile vitron) and machined retainers fit the buick engine?

Question 2: If not, does anyone know where I can get some for the buick?

Thanks,
Chris
