It's a shame they didn't opt to do something about the rocker shaft stand pad height, or at least make Ford spec ones a factory option!

It's really a non-issue.  T&D now has a TFS rocker.  Harland Sharp rockers bolt on without any modifications and now there are stands available from sources like Precision Oil Pumps that are offered in shorter heights if necessary.  I've used pretty much every rocker that is available with the TFS head and it's just a matter of adjusting the stand height to get the correct geometry, just like you would do with any other FE cylinder head.

There is a good thing about the raised pads, they are drilled and tapped much deeper and allow for a much longer stand stud (deeper engagement) than other heads.  I did a 445 with a solid roller a little while back and just used a longer base thread stud coupled with some T&D rockers.  No issues there with about 650 lbs over the nose.

The only bad thing about the TFS heads is that they're not currently available.  Otherwise, you can't beat what you get for $2650, while featuring PAC valve springs, and other quality parts.   For what you have to pay for other brands, if you had to buy a set of rocker stands or modify a set, it would be well worth it.

The point Brent made about the raised rocker stand height on the TFS heads is a valid one. The rocker stand bolt holes on the Edelbrock heads is very shallow, and there are numerous stories of people puling those few threads out of the head castings, often causing valvetrain damage in the process. It is great that the BBM heads are currently available, a couple of years ago, I was trying to purchase a pair of BBM heads, but despite waiting almost a year, there were none to be found. Luckily, I was able to find a pair of TFS heads, and although I have to change out the valve springs, since the only heads that I was able to find were hydraulic roller psec springs, which were too stiff for my flat tappet cam and lifters, but at least I did get a set. I am using a set of ISKY iron adjustable rocker arms, with the POP rocker stands and end supports, which I bought from Brent, which he had machined .220"  shorter, to meet my needs. Even when I bought my TFS heads, they were in short supply, and had been on back order for quite some time, so I got lucky. Now that the BBM heads are available, if I was looking for some aluminum FE heads, I would jump on the BBM heads ASAP. You never know if the supply of BBM heads will dry up again in the near future. As they say, a bird in the hand is worth 2 in the bush, and everything that I have heard about all the FE parts made by BBM is top notch.

TFS is telling me 3-4 weeks.  I’ve got a large order of the hydraulic roller heads and some bare heads ordered if anyone wants some of the 360cfm ported heads that we do.

When the TFS heads came out, there was grumbling about the taller stand surfaces, and some were machining them down to match up with the usual stand length. It never made sense to me, as it seemed better to keep the solid head material taller (and have more thread engagement) and shorten the stand, as it is just a chunk of metal with no clamping force, and it's length is pretty irrelevant to strength. The problems that some had with extreme spring pressures on the Blue Thunder setup would seem to reinforce this

Just got my shipping notification for the Trickflow heads I ordered at PRI.  Hopefully that means a steady supply is not too far off for everyone.
