Just want the best bang for the buck, but also i want whats ideal for my 272 cams.
Ive heard that BC1100 springs are good? any thoughts?
Also what retainers are good recommendations?
Are Manley retainers any good?
 
Stock springs and retainers are plenty as mentioned. Just make sure they are in GOOD condition.
With a brand new Oem head, with brand new oem springs I would float them over 35psi of boost, at as low as 5,000 rpms. It was the exhaust back pressure floating exhaust valves. I threw in a set of bc1100's and it was fine.
 
Which cams? My Galant has made 700whp+, 40psi+ on these Web cams (a little aggressive than OP's 272s), 9,000rpm revved all the time including on the dyno. It has Kigglys on now, but I have S3s in it too. I have ran stock springs hard and never had an issue.

Just some fp2's. The car would rev fine to well over 8,000 at under 30 psi. Cranking up the boost would float the valves.
 
ok thanks all for your input i think im just gunna upgrade, they are not that pricey for some decent springs
