Yeah I was hoping I found the dark secret in 7.3 performance to keep headgaskets from blowing, unfortunately not.
Block and heads checked out true with straight edge.

Yeah I had a hard time believing it was normal. I have seen many head surfaces, and my dad many times of what I have, and it was a first... over on PSN someone called it corduroy... lol.
Here's the plans, heads were resurfaced(needed about .005" to clean up heads completely, valve recession still good), New H11s, stock head gaskets, Smith Brothers pushrods, shimmed Comp 910s. Honed cylinders and re-ring with rod bearings. Modded H2E will be going on with Bean's brass up-pipes(pretty sure they've been leaking
some since I got the truck, spoolup should be near instant compared to the sledgehamer. Even though piston protrusion checked out, I changed out the connecting rods after reading this post over on PSN about a person who had a nearly identical situation I did.

*I* wouldn't chance it...ever.
cause *I* have personally pitched a rod that checked out dead nuts tits, was shot peened, checked for bend/twist & magnafluxed ...came out of a cyl that had popped a HG...went back in the same cyl...then came through the block in 3 months...and have seen the same over and over w/ customers who pop a gasket...THEN do studs, LOL...
then pitch a rod.
and arp's aren't on my short list for head studs... |
One somewhat of a budget and but doing a decent amount of work I'd be kicking myself immensely if a rod ever threw. Feeling a lot better after changing them out. Should be up and running by Wednesday night I'm figuring.
