So I bought a set of AFR 185cc heads for my 347 build. The heads have springs on them already. Im most likely going with a Comp Cam (XE274HR) camshaft. Comp Cam offers a package that includes springs along with its lifters and camshaft.

My question is... Should I stick with the springs that came installed on my AFR heads or should I purchase the Comp Cam kit with their springs? Will there be any difference at all or am I over thinking all of this?

call the techs at comp and tell them what you got so you ensure you are getting all the right stuff

you should use either the 986's or 987's, I ran a xe 282 for a while in my 347 and for what it was it did well, then I went custom, If I were you I'd run the xe 282, heck if your interested I still have the 282 and the 978 springs and cups I used in my afr 185's, pm if interested
