Very well said.

yep, couldn't agree more.

After a couple of months I got my head back along with a set of T&D rocker arms.

Didn't T&D supply a wide hold-down for the second inboard pedestal?

No, the kit came with all narrow hold downs. I sent them an email asking about that. Also the hold down studs are too short since there are threads exposed in the nuts. I shipped them a Trick Flow head to use for mockup but they must not have done a trial fit. Not sure what happened, hopefully I'll find out once they get back to me.

Studs too short, some of the hold downs not the correct width.

There really just isn't any excuse for that.

Some sort of miscommunication I guess. I sent them a cylinder head but evidently the guy doing the design didn't use it. I'm sending the rockers back to get reworked. They need to change the hardware and make some new spacers and hold downs. The rockers also need to get a spring relief machined in them since a few of them rub on the springs. Should be back up and running in another week or so.

I guess you're more used to having this type of thing happen than I'd be.

My thought was, "Dude...... You had the head there!!!!! How could you get it wrong???".

To quote my builder again: "If it comes out of a box, it's FUBAR"

That is almost exactly what I said! The guy knew he made a mistake as soon as I sent him some pictures showing that the parts didn't fit on the head. They screwed up, maybe too busy to pay attention or new employees or something else. Hopefully they get it correct on the second try.

Hopefully, t&d is my personal favorite rocker.

How's the sweep pattern with the T&Ds? They look like they're biased to the exhaust side of the valve tip in one of your pictures.

Sweep looked good to me. These rocker arms are a tad shorter than the standard 440 rocker arm. Similar to the Harland E rocker I assume.

Finally ready to dyno test the rocker arms. I have 1.50 rockers on the engine now which I'll test against these 3 sets. From bottom to top we have 1.60 MRE rockers, 1.65 T&D and 1.70 Harlands. Guess we'll see what happens. Took me 3 months to get everything lined up. The T&D were custom made as were the Harlands. But now that I've had them made anyone should be able to call these guys up and get high ratio rocker arms for Trick Flow heads.

Andy - You've got more than one of my mortgage payments in rocker arm assemblies in that picture!

But wait, the rocker arms each require unique length pushrods so now I need four sets of pushrods at $180 per set!

I think the total tab is roughly $3000 when I add up rockers plus pushrods. And it will take a couple days of dyno time to do all the testing so there is another $1000 plus fuel plus having to take time off from work.

Adds up.........

Hopefully the loaded rocker ratios and net valve lifts will be provided .

I have pictures of most of the rocker arms fully loaded but now that I've changed springs I'll need to redo them. Not a big deal, just takes a few minutes after each rocker change.

Looks like T&D got it right the second time around. I'm going to order pushrods with oiling and oil these rockers arms thru the pushrod. Just seems to me that it will work better that way since that is what they are designed to do.
