Out of the box.
Best flowing sbf heads.
The bottom line is that every head in our test has seen varying levels of success and failure so it would be foolish for us to say brand a is the best head since on the wrong engine the results could be terrible.
We wanted to include the biggest baddest heads possible and afr is known for making the best heads in the industry.
They re all junk.
Still don t compare to aftermarket stuff but not bad for production ford heads.
Same as the 302 heads from there on from what i ve seen.
The edelbrock 60069 is one of the best sbf racing heads that offer 428 cobra jet sized valves for street use power.
This cylinder head comes with amazing intake and exhaust runners that are cnc profiled to help your truck to act well.
To pull this off we needed.
If it sounds.
It is also good enough to try out if you want a great flow cylinder head.
Put you some 1 94 1 50 s in there and clean up the ports a little and you ll have a decent set of iron heads.
6 afr 220cc sbf last but certainly not least are the afr 220cc heads.
Has anyone seen or made a comparison chart of advertised numbers for aftermarket sbf heads.
I believe in 77 d7 heads they went to larger chambers and smaller ports.
These ford cylinder heads all feature between 170 and 180cc intake port volumes and offer excellent performance potential over even the best production iron 5 0l heads.
Get out vote this november.
In my opinion afr and trickflow make the best windsor heads and hp per dollar trickflow wins.
These heads feature absolutely massive 2 100 intake valves but marginally smaller 1 570 exhaust valves.
