Pretty sure it’s the alloy of the heads that absolutely demand bronze liners. I just went through this with some EQ Chev variants. Looks Like your testing @ Daryls place. Seems like a good operator. Good luck. J.Rob
I will be dropping the heads off at the machine shop in London tomorrow for repair and guides. Will I need another valve job because of the guide work?
I was testing with Darrell, he’s great and has a ton of experience. Huge Mopar guy with some nice rides of his own. Very cool experience and I learned a lot from him. Glad he had a good ear and fast reaction when the valve stuck.
Piston got dinged and some minor damage to the lifter and rocker arm. Push rod was toast too. Hoping to reuse the piston and rocker arm. Will need a new lifter and push rod, maybe the dog bone too.
