With the as supplied springs??


Yes, I have the Trick Flow springs and retainers on my 240 heads. The 270 heads switched over to K950 springs when I put the super aggressive cam in it. The roller cam springs with the Ti retainers are high quality parts. Should be fine for most bracket type roller cams.
