AFR 165's would be my pick if I was changing heads again. They still have a small port volume to keep velocity and torque up but flow really well too (around 250cfm from memory). They cost around $2500 for a set last time I saw them.
I had to port my Edelbrocks to make 300kw with a 302
My AFRs cost $3,000, but they cost about $200 more than that now.
If you get stud mount heads you will also need stud mount roller rockers. (if you have RR's now, they are most likely pedistal mount) You really need stud mount if you want 300kw to support the stronger springs and revs required.
Like i said, its just money. How fast do you want to go?
yeh i was expecting that kind of price Racer. accoording to AFR ~1750US for the 165s with valves/springs and 25 more for the 185s. ideally, my 300kw figure will be attained with 347 cubes and hopefully under 6 grand.. if it means, say, i get only 280kw after stroking coz i gotta run a conservative cam and redline at lower revs then so be it. i dont want a screamer, just a nice strong street motor. but right now, i jsut want good heads that i wont have to upgrade later on.
how fast do i want to go? faster than i am going now. want to hit low 14s after doing heads/intake/cam/RR/TB/MAF, and later low 13s. one step at a time tho, and my first step is heads. AFR 185s seem to be the go yeh?
