Building a blonde young beefcake wearing nothing but skimpy shorts named Rocky
lol I seriously cringed when you text me those pics Bryan
This is why I don't spin any of my econo-built motors past 7k
Or push a gt3076r to 25+ psi
"you're gonna have a bad time"
The up side though is that now it will be completely built and ready to make some nasty power.
I agree with both Bryan and Leo to a certain point. On the one hand plenty of people are making over 300 with stock head/valvetrain by keeping the limiter at 7-7.1, on the other he clearly had failure due to valve float (or so I'm convinced) at high pressure, flow, and rpm, so......

Picked up a new 2003 cylinder head. It was in great shape to start with but I quickly gutted it and had it decked and a valve job done. Then I installed the Supertech goodies – Dual springs, titanium retainers and valves. Now she’s sitting there waiting for the coolant reroute material and to assemble the rest.
Ordered custom head gasket – Thicker .060” mil and a replacement CP piston. There was damage to the other 3 pistons but not anywhere near the way this guy looks:
It also turned out that my block was basically junk. After dropping the piston number 4 out I noticed some rather large dents in the walls.. Not worth trying to repair and even going a couple sizes larger in piston would likely not solve my problem. So.. SQUARE ONE.
I picked up a bare block and dropped it off at my machine shop.. They are going to give me feedback on the 3 pistons that have seen some damage and I’ll go from there.
If the other pistons are junk I’ll likely return the one piston that matches and bore it over as large as I can get away with. Not the best way to make power but I’ll be able to get away with better clearances and have more surface area on the walls…
