Edelbrock Head Selection

I run ported Eddy rpm heads with the small valves and they are excellent..however that's on my 306 so I'm limited on larger displacement experience. I can only say the quality is not a issue and the product is excellent, really only comes down to price and what if your after performance wise. I can imagine the AFR heads would produce somewhat more power (how much I can't say) but reputation speaks well for Eddy heads on pretty much every application they've been used on.

Exactly what I did! the savings from buying the Eddy heads over the AFR's freed up enough cash to pay for my cam selection and what the builder charged to work the exhaust side of the heads a touch (he was VERY helpfull and reasonable). End results are excellent flowing heads and dyno numbers that convince me a swap to AFR heads would yeild little if any gain...the AFR's though an excellent head no doubt really only offered me a 300-400 price over run in my budget for what I wanted. I'm sure as I stated before the AFR's likely would shine brighter for HP numbers but for the regular old street drivers like myself you're not going to 'FEEL' the difference anywhere but the pocket IMO.

I'd use edelbrock victor jr's for your 347.

The afr 185's will EASILY outshine regular edelbrock performer rpm heads.
