You didn't get dissed, Mike. You don't know if clearance will be an issue until you know the shaft is at the right place. Then you can rightfully determine whether the beehive springs need to be used. I call that being informed. There was no disrespect given, at least not from me. Yes it can...

That is incorrect, Rob. The Harland Sharp rockers need more correction than most, even on the TF heads. Throw a set of T&D 8130 rockers on a TF head, and run .700" net lift, and you won't need any correction. Outside of that scenario, it will need adjustment, just not as extreme as other...

If budget is a concern, just use the stock rockers and measure for the correct length pushrods. The rollers are a great upgrade, but they have to be set up right, which means relocating the shafts. That adds to the cost and makes the rollers less budget friendly, especially when you could make...

Yes, I am. And I'm at Carlisle every year too.

Just north of Hershey. I can't do an estimate/quote without knowing what I have to work with. That comes with tear down and inspection.

Sorry Mike. I think you misunderstood. I have cores in the event that some of his parts are beyond repair. He asked about an engine builder and I, as a builder, was just pointing out that I have those parts if needed during the build. I'm not trying to sell him parts.

I generally encourage leaving the engine assembled for delivery. During teardown I can determine the health of the engine and recognize any issues as currently assembled. The engine will tell a story of its life during disassembly if one knows what to look for. It also reduces the risk of lost...

I'm in PA and have some 273 cores in case additional parts are needed.

Mike, I believe you must have misunderstood me, and I don't want others to get the wrong idea. The Trick Flow heads have the rocker stands repositioned for to have geometry more suited for a roller rocker. It can't be right for every application, but it is much closer than other heads on the...

The radius for the shaft is not machined properly. Check out some recent Speedmaster threads to see discussions about this issue.

Only if the stands are corrected. Then I have no problem doing them.

Just an afterthought. Lay the gasket on the heads too, using dowels for alignment, and see how it looks. Between the block and the heads, the gasket should make it obvious which one is "off".

Hey, the Trick Flow people are human too, and can make mistakes, so the heads could have a problem I haven't seen. I just wanted to save you some grief exchanging out heads if that wasn't the problem. Let us know what you find.

Yes, the gasket will go on without issue. The holes are extra large. I'm not saying there couldn't be an issue with the head, but my experience was that the holes were shifted in the block. Being a TF dealer, I do quite a few builds with them, and haven't had a head with improperly located holes...

I have experienced this with Trick Flow heads before. It is likely not the head's fault. To have room to CNC the ports as large and straight as possible, Trick Flow machines the bolt holes on the small side, but plenty large enough for the fastener. The problem is that the factory bolt holes in...

Nah, I knew what you meant, Geoff. To be honest, I was expecting a fight, so I was purposely vague. My apologies. When I set up to cut the rockers, my intent was not necessarily to lengthen the fulcrum, but to have the rocker resting closer to the center of the valve stem, in the perpendicular...

Yeah, but where is the high spot on a radius? Up, down, left, right? It has to have context.

Essentially, that's the effect.

Thanks Jim, but I don't have to be credited. I was just trying to make them usable and fit reasonably well. I wasn't sure if I mentioned the increased fulcrum length to you, but when Dwayne mentioned the ratio accuracy, it reminded me that I did that, and it probably had some beneficial effect...

They might be a little better than they were originally. Since I had to restore the radius on the rocker tips anyway, I cut the fulcrum length slightly longer so the rocker would center on the valve tip a little better in his application. That would have the effect of a very modest ratio...

One of these days, I'm going to have to do some YouTube videos about rocker geometry. There is some good basic info in these, but also much that is incorrect. I wonder if either of these gentleman can explain how the centered pattern improves reliability or performance, or any other benefits...

I have a few sets of TF's.

You would be surprised at how much tweaking they still need. Sure, they may fit nice, but unless you are lifting the valve to .800"ish, the shaft will still be too low.

The only other way I knew to do it Duane, was to relocate the bolt holes on one head, and then deal with the oiling hole for the rocker gear. I didn't want to get into that, especially with all the other work they needed, so the different stands was the logical way forward. The rockers are...

LOL! Ha, I can't remember everybody, even though I try. Glad to know it was addressed.:thumbsup:

This was mentioned briefly in post 61, but nine pages in, has not been addressed since then. What was done, or checks made to ensure the valvetrain was properly set up to remain stable?

They are better, but I've found that none of the "cheap" heads are really a bargain. Until you get everything right, with components you can trust, the end cost is very similar to more expensive heads. That being said, I understand budgets so you get the best you can afford. Sometimes that means...

The Comp rockers are a good choice. I prefer the option of higher ratios not available from Comp, though. Just an FYI for those interested, adding lash caps with a roller rocker will actually make the true running geometry worse, regardless of where the pattern is on the valve tip. See our tech...
