Trick Flow small block heads

I hope to find out
I have a 418 that should come in around 12.5 to 1 with trick flows.
Figuring on something about 268@50 with 640ish lift( solid roller) 4150 style carb and the trick flow intake
Likely use the small Doug’s headers i already have.
Gonna be dissapointed if it doesnt make 600 and run low 10’s in my close to 3300 with me car.
Hoping to shift it at 6600-6800 ish
This all assuming my hip replacement next month goes good and i can get this together next offseason. Had planned on it this year actually. Might work out well that i had to put it off a season.

I would think to get that, you are going to have to do a bit of work on the heads. It will probably take a 2.05 valve and some blending and I'd think if you can get a bit more lift it would help. Much of .600 lift is difficult with OE valve gear.
