I appreciate all the advice.

AFR also mentioned a 4 to 6 week waiting list for a set of 180s or 195s.

Ive already got the short block assembled. I wasnt too thrilled about letting it sit partially assembled for a month or more so I decided on the Edelbrock performer RPM's.

I read an article in Chevy High Performance, it is also available online.

Can I expect similar torque numbers with the Edelbrock heads instead of Vortecs? Are the springs on the performer RPM heads too stiff for breaking in a Comp 270H flat tappet cam?
