Dec 13, 2021 · Hi all, I've got a 327 from a 68 Corvette in my 66 Malibu street car, stock bottom end, running an unknown cam and 882 heads. Currently running an RPM Air Gap intake, 600cfm carb, Hooker headers.

Feb 17, 2022 · I see reviews on the NKB heads, but they are all from like 2016. That's enough time for the heads to get good, or bad. I haven't found any good used heads local.

Apr 15, 2017 · I know this post is old, but its hard to find any feedback on the skip white NKB sbf heads. I'm currently running them on my 88 mustang. The car ran best of 11.98 @109 in 1/4

Jul 26, 2016 · Dual-plane, high-rise intake with 750 carb, 1 5/8" long-tube headers. Not too bad for a budget 355 motor, 460/475. The NKB heads are the least expensive aluminum heads that are currently available anywhere, although the Speedway Motors Flo-Teks look attractive too. I will also post this combination on the wiki under Dyno-Sim combinations.

Apr 2, 2006 · My response is, it depends. A 200cc head would be overkill for a fairly stock 327 with a small cam and tall gears. You would be better off with a 170 or 180cc head based on your performance goals. It would be a great head for a high compression, high RPM, low geared light weight car with a 327 cubic inch smallblock. Street or track.

Jul 22, 2017 · My car is a 1989 LX convert. How much cam lift will they tolerate? Will my stock valve covers provide clearance for these heads? Any recommendations for a cam for street use.? Nothing too lumpy, I want to drive the car and not pose at stop lights. Run like the wind.

Dec 17, 2013 · As far as I know the NKB head is only available in the SBC as of right now. Far as I know, there isn't multiple sources for the RHS/Pro Topline clone head. There are other import heads, but they don't look like a RHS/Pro Topline.

Aug 12, 2014 · skip white is discontinued using the procomps in his builds and I think he is clearing them out of inventory. because as he put it the newer NKB (also china based) just perform way better for the same price .. its all in the last link I posted.
