Hey again fellas, here lately, I've noticed several places poo-pooing the Edelbrock RPM heads (not here specifically)...basically saying they're not worth a damn...now, I've never had any of the other heads (TFS, World, Dart, etc, etc) but going from a set of ported E7TE's to the Edelbrocks for me was a night and day difference-there wasn't one aspect of the performance I noticed that didn't get better. I understand that AFR pretty much has the best port profiling (duhh, CNC) and what not, but after a short examination of some of the running gear on the AFR 185's, I discovered they use "ok" springs and heavyweight valves...even my machinist said they use sub-par springs for anything over about 6,000rpms-because of the valvetrain weight-in roller cam apps.
also, probably about a year and some months ago, MM&FF did another one of their famous "head comparo's"...according to what they found the 'brocks didn't do terrible by any stretch of the imagination...of course, since AFR's made some of the biggest power gains by fair comparisons (by port volume), it seems like everyone said ptooey to alot of the other aftermarket head mfr's, with the exception of TFS...they still hold their own quite well. I personally have never had a moments problem with mine, and I didn't have to buy specific rockers or pushrods to swap them.
I guess the point to this one is, what do some of you more tenured engine builders/speed enthusiast's prefer? Based on impartial research, which ones are the best for the average enthusiast to invest in without breaking the bank, and able to keep longevity?
oh, and will they be "enough" for my upcoming forcefed (8-12psi) 331 build up? jk guys, I plan to have them worked a little bit...
