Survey On Whats The Best Set-up.

Ok. I'll go with you on the latest TFS heads seemingly having an advantage. That's why I said I'd build that way with a from scratch build, today. However, AFR not coming close? I'm open-minded, but that will take some convincing.

So, perhaps you can show me something more up-to-date than but in the same style as this old article?

Richard Holdener did stuff the right way. Same day, same motor, same dyno with a full run down of all of the specs and parts involved. The TFS head in this shootout made a negligible bit more power over the AFR.

AFR and TFS have changed their game up, but I've not seen anything like this in a long time. Have you?

Well, the engine master vid is not real world in my book. How many members on this site have a 410 CI stroker stuffed in their fox body. Was looking for more data points than just one engine to see what is really correct.

But it is real world. If you want to make big n/a power on pump gas.
I thought about HCI for instant gratification,thank god I didn't. Saved
for what seemed like forever,for a Dart block 427,TFS heads,ported
super vic. Blah,blah,blah so glad I did.

Biggest head and exhaust you can afford, custom cam and intake recommendation from cam grinder.

The engine masters compare was interesting, but not realistic in my opinion. 220cc heads are not big on a 410" motor and the cam seemed to be what was lying around.

Just wanted to start a discussion on what is the best set-up for NA cars. Should you run bigger flowing intake port heads with a small cam or a bigger cam with a smaller flowing intake port heads?
Opinions?

kind of a loaded question.
The larger head will offer the same power as the smaller head with better drive-abilty and less requirement for rpm.
Start throwing the same "better" drive-abity requirements at the smaller head, will require "less" cam, and now the smaller head starts giving up power.
Allow the large head to have similar drive-ability (more "wild") as the smaller head, and now the larger head is going to make more power than the smaller head.
This is providing the inlet and exhaust is correct for each.
It's a juggling act.
Back in the day, to make good power you had to have a wild cam, because, we didn't have the "big" heads that are now available, since most folks don't want a wild cam, we didn't make big power. Now, we have the big heads, and people can run a mild cam, make power and still have nice idle and drive-ability... it's all the rage.
AFR vs TW... really comes down to what you are wanting to run for a piston. I quite like my pistons, so, if I were going to buy heads for my 306 I'd go with AFR Renegade 195's, throw 1-7/8" headers and 3" exhaust on it, port the heck out of my Victor and I'll assure you all the TW guys would wonder what happened. Nothing happened, I just selected the head that best matched the pistons I'm running.
Again, it's not just the heads... it's everything...
If I wanted to run some other piston (or a stock piston), then maybe the TW's would come into the mix...dunno, have not looked into it.
