valve spring retainers

[aussie]

Just got a new set of dual springs , 250 @ 2.000" and new titanium retainers. The question is the inner spring to retainer dimensions are not even close. The retainer is .100 smaller than inner spring id. Should i be concerned? Thanx

Who's valve springs, and who's retainers ?

I bought them from dart. I am not sure what brand?

The springs should fit the retainer fairly close. Most of the time pictures are better than words, so go to the Manley Performance web site, click on Master Catalog/Cylinder Head Components, scroll about 2/3 the way down and you will see how retainers are sized so they will fit the springs. All the retainer manufactures have this information available, I only refered you to Manley because they have the best pictures.

So I have just purchased a set of Dart 18 degree heads for my 406 SBC. When I see the 15 degree heads that are offered I am curious if they are a head offered for smaller cube motors because they are able to get the chambers down smaller or are there any real advantage over a 18 deg with the similar layout of the head and a few degrees different valve angle. When do you choose the 15 deg head over the 18?
