2019 mustang GT whipple build of new motor

[Peedystablo82]

I have the Whipple Gen 5 3.0 and pushing around 1k whp and 817 torque right now. My motor is completely stock and it's holding up pretty decent for right now.

Obviously, this won't last for long I'm assuming and I don't want to be down for months. I got a good deal from a very reputable dealer that is going to supply and build me a bottom end with sleeves to handle 1500whp.

I'm looking for my motor to handle between 20 psi and 23 PSI. Bottom end will be good, but what are your recommendations for the top end. I'm assuming upgraded valve springs would be able to handle 20 psi, but would I have to upgrade anything else in the top end for it to handle 23psi or so? Any info would be greatly appreciated.

Some kind of o ring, embossed or beaded head gaskets for sure.

I'm sure I'm gonna need valves, springs and retainers?

That is recommended. Increased seat pressure, heat and RPM will fatigue the OEM valves. Valve related failures on big power boosted coyotes is a concern.

Getting my motor done by Will at RPG in Fresno, CA should hit him up. I am going w the 5.2 Predator GT500 Block

If the stock valve springs are holding rpm now, then just a refresh with stock springs will do. I'd be more concerned about too stiff springs collapsing the lash adjusters than boost blowing the intakes open. On the exhaust, boost doesn't affect how the springs work.

Yeah, my car only has 3,500 miles on it. So I'm assuming the springs and everything are still pretty good. my car is actually going into the shop this week to get the McLeod clutches and circle D put in along with the ice tank and a few other things. My built motor is coming soon though and I just want to make sure I have everything in order when I do this.
