AFR & Trickflow are about the best heads you can get for a SBF out of the box. I prefer AFR but he TFS heads are top notch also. You will pay a bit more for either over the Edelbrock heads but you get what you pay for.
I’ve run both the Edel 6037 and the AFR 165 on my car, and in my experience the AFR is the way to go. Both make great quality parts, but out of the box the AFR’s are tough to beat.
If I were to be in your shoes and was looking for a H/C/I combo I can’t stress enough an AFR 165 with an Ed Curtis custom grind cam from FTI, and pretty much any aftermarket intake (with exception to the Cobra and GT40). A couple of my friends were some of the first customers Ed Curtis ground cams for, and in there street trimmed foxes ran 11.7’s @ 117mph with the bolt-on combo mentioned above (back in 2001 or so).
FWIW…both these guys had been using an Edelbrock 6037/E303 combo that were running a best of 12.3 @ 109mph:)
It is a well established fact that AFR heads out perform Edlebrocks, especially when referring to the 5.0 SBF. Idk why anyone would use different considering how affordable they are for you Ford guys… AFR heads for LSX cars are $2200 and up, and thats the cheap “top notch” heads, TFS and ET’s are even more.
