Spring upgrade time? https://www.f150forum.com/f11/heads-have-come-off-refresh-spring-upgrade-time-585001/ Mon, 11 May 2026 01:03:42 GMT I've got the motor coming out of my '19,RCSB and it's a total white "I'm in there" situation.

Prior owner said they burned some rings racing, put a new motor in and when they were timing it, either got the timing wrong or stretched a chain/snapped a guide.

I'm not going to take a chance, so out it comes and I'll drop in 10:1 pistons, new bearings, head studs, etc... and since the head is a risk, I'll go through it or replace it entirely.

While the head is being inspected/replaced, what springs do you guys recommend for a stage 2 Whipple boosted rig?

Lookin to make mid 700 wheel on pump and won't be spinning it much higher than 7k, I wouldn't think.

I'm thinking:

Manly piston and rod drop Ins @ 10:1
ATI damper
Already have billet oil pump and crank gears
Deatschwerls DW400 Fuel pump with wire upgrade
ID1050 injectors

Anything I'm missing?

Spring recommendation?

Thanks, gang!
