Well
My car is slightly different since it has ported heads but even when I was on the base 727 package my stock tires where ice skates
I have some 305/35/19 g2/555 buttons about to go on it but until then I drive like a grandma
I have opg and tg upgrades along with a car back that suits my needs
We could always port the heads
I just got mine back together and it's very noticeably faster/quicker
And I lost 3 psi doing it
So I'll be popping the ati 20 percent of dampner on now along with the upper pully needed to get me to 15 psi then I'll have Travis tune it
I'm shooting for 15 psi at the end of all this
I'm expecting to lose 3 psi or so with the ported head
Hence the reason for the overdrive ati dampner
I'll repully the head unit once I determine what the current psi is at
The car will also be running the id1000 and tuned/retuned by Travis at...
Phase two
Mt82 car
Ati 20% od
80mm pully
Aluminum flywheel
Rst clutch
Ported inlet on tvs blower
Ported heads
Arp studs
Soon to be back together
And 331 gear swap
Those valves are ferrera one piece stainless valves
These heads arrived with them already in it
We flowed the head with stock valves and picked up 5 cfm btw
Minimal amount
I don't want to start affecting cam timing or changing geometry too much
So it's just going to be a clean up pass
I'll cc the chambers for u
We left the chambers as is. Just removed the steps
U shrouded the valves a bit yes. But as you can see from the scrub the chamber is almost at the bore size
