Not sure on the intake. I'll call Holly and see what they recommend. I want to do their Dominator EFI. 327 gears. Weekend driver, sometimes track 1/8 and 1/4> Still got a long way to go but i'm piecing it together. These heads are brand new and half price.
depends on you goal but if you turbo it. they will be ok. the flow similar to the AFR 185 heads.
if you want a monster then but afr 205's but it will have a bit less bottom end.
they may require special headers because they have a raised ex port.
the car will be a pig with 3.23 gears.
