Re: Brodix heads massive guide wear
I have an adjustable pushrod and mock/measuring rocker arm. I also mark the valve tip and turn the engine over by hand to mark a pattern on the tip. All is good.
I haven't called Brodix yet but plan to. I may also take these to a local machine shop for analysis assuming Brodix doesn't want to see them first. And I may just replace these heads with a set of AFR heads and be done with it.
One thing I discovered in the past is that the rocker arms themselves can make a huge difference in geometry. I once built a big block and assembled it with Harland Sharp rockers. The engine needed custom-length pushrods at that point. A buddy came over with some Crane Gold rockers and we installed a pair. The geometry was perfect with those rockers.
I'll spend some more time doing some sweep analysis and use whatever provides the smallest sweep that is centered. I've never used Scorpion rockers before (usually run Crower stainless), so I hope they aren't the issue.
