Anybody running aftermarket heads had them crack like this before?
After two years of running great just clank clank clank when I was running in one morning.
Motor only revs to 4300 and the heads were ported, decked, rockers, rods, and new valves/springs.

P.S. anybody have starboard stock head lying around ?

Maybe this is why some reinforced this area with welding.

This is the very reason why Hoyt @ GatorTail reinforces the rocker bridge with weld.

is this a roller rocker issue? or factory rockers do this to?

Factory rockers do it too, but double wound springs and heavy ass rr's don't help any.

F*** this is what I get for not being on the forum for a while, where do they reinforce with weld? Or let me guess... Exactly where mines broke.
And I bought them slightly used a long time ago

Is that EVT RR's? Isn't this only a problem wif double wound springs? Just asking. I'm curious.

Heavy rockers and double wound springs.
