The Wonton

Those poly locks still clear the valve covers? Nice.

Glad to hear you are getting it sorted out.

The pushrods were labeled 7.650/8.700 like planned correct?

Its interesting they were longer, as often they can measure slightly shorter because of the oil holes.

This is probably good because I think he could use longer but was afraid to test without adjustable pushrods(that can get expensive).

Yeah, I didn't think the poly locks would clear either. But we threaded one on and left it a couple turns above zero lash, then test fit the valve cover. It still fit. Once it was all said and done, if you bop your hand on the passenger valve cover, it "kinda" sounds like it might be tapping up against one, but it's quiet when running.

I did snap a few exhaust valve pictures, showing no, mid and max lift:



Maybe I’m just crazy, but there seems to be more sweep across the stem now. But it's not focused to one side or the other.

Some full roller rockers or even some roller tip rockers would be a good next upgrade, less friction, can cause less wear on the guides, and less flex for more actual lift.

So is this rig running good again?

Yes! I’ve put a couple hundred miles on it since we messed with the valvetrain last, haven’t had any issues.

It's the ARP adjustable stud kit to replace the non-adjustable setup that was stock in gen5+. I hadn't noticed how close the sleeve was to bottoming out, but no, it isn't bottomed out. I will double check the slot/sleeve relationship, but I think there's plent of clearance.

As for the seals... yeah, I was kind of disappointed to see the unbrella seals. Jon took the heads to Ault & James in Dayton Oh which has been a respected shop for many decades and did good work for me a few years ago. However, I don't know what Jon discussed with him for work to be done.

Ault and James have been in the racing biz a long time..

Also….where did you find the elusive double hump BBC heads?
