I posted a while back about my brother in-law's new 507 c.i. stroker with Trick Flow heads and HS rockers for the standard BB head. We heard that the HS rocker was too long and the scrub was jacked up. I finally got a chance to mock it up. It really wasn't nearly as bad as I expected, and I think we're going to run it as it is. It's got a .600" lift Lunati solid roller with the TF 240 heads and won't see any extreme rpms or crazy valve spring pressures. I went over to his house this weekend to degree the cam and help him decide what to do with the rockers. I wanted to get some other opinions on what you would do with this. The scrub picture isn't the greatest as some of the dry erase marker flaked off, but you can clearly see the scrub line slightly biased to the exhaust side. It's about .025 from being centered.

If anyone can help with why the pics failed I'd appreciate it, lol.

Call Mike @ B3 racing, he makes custom offset correction spacers.

CSK nailed it. Stop screwing around and call Mike. You'll be glad you did. I can't see the pictures, but unless the sweep is .040 or a bit less, you need to fix the geometry. Centering the sweep if it's .080 or more wide doesn't mean a thing.

Who's "screwing around"?? I spoke with Mike over a week ago and we had a very long discussion about this and lots of other things. He's a great guy and I really appreciated his time. That being said, I'll mock things up and look at them myself before I make any decisions. The scrub was .037 wide, .123 from the ex. side of the valve to .183 from the int. side on a .343 o.d. valve.

If the pattern looks good to you then run it. You shouldn't have any issue at 0.600 lift. I never needed anything special on any of the Trick Flow dyno motors I built and I ran most of them at 0.750 lift.

I'm glad to see others on here not drinking the cool aid on the rocker arm tip shrub patterns having to be no wider than .030 directly centered on the valve stem
if it is centered, or almost centered and .060 wide I'll run that in a heartbeat

Misread your post then. I couldn't see the pictures. Maybe if I had my response would have been different. If the sweep is that narrow, run it. Being centered doesn't mean a thing.

.060 is too wide. Why leave it like that when it's fixable?

All good man, I know you were just trying to help. Sadly I still haven't figured out why those pics won't show, LOL.

Centered" is at the bottom of the target list.

Note that Mancini's website lists the "E" version of Sharps (edelbrock) for Trick Flows too. Went through the same dilemma for my stealth heads. Switched to Edelbrock sharps, no fuss, no muss, no shims, no adapters, no BS. Just a good scrub pattern.

Yep, we got back with HS and they were very kind in offering us an option to "swap" them his old rockers+ $$ and they're sending out the "E" rockers. They really owed us nothing, so they did it simply because they're a good company I guess? Either way hats off to HS for their awesome customer service.

That's awesome, glad it worked out. Shanon's worked a similar deal with HS for me. They're great to deal with.
