Good to know, are there any other supporting components i should order as well, and thanks for the help this late at night!

 

By the way i've got self aligning roller rockers 1.6 going on if this makes any difference in the parts i need, thanks.

 

The only thing I can think of: You will need to make sure the tabs on the rockers (that keep them aligned) don't interfere with the retainer.

 

yep, the PAC 1218/1518 springs have 145 seat and 340 open at 1.750"

I believe that Comp has changed the 26918 entirely and they have less seat pressure and more open pressure now but I have not had any here to actually test. This is just based on what I hafve read.
