LEMONS HEADERS INC.
’64 thru ’67 CHEVELLE PRO TOUR BB
Part #BBPT-610
Header Spec’s:
This header is available in a 2” or 2 1/8” tube size with a 3 ½” collector. All of the tubes are inside the frame. Our headers are hand made to order, so we can build them for any engine deck height and for any aftermarket cylinder head as long as the engine stays in the stock location.
What Fits:
On the ’64 thru ’67 Chevelle chassis, small block frame stands for the front motor mounts are required. We used Prothane engine mounts #7-504 to design with. The header will also fit solid motor mounts Moroso #62530. Does not fit a mid plate.
This header has excellent ground clearance. We used a Milodon low profile 7 quart oil pan #30951 or #30956 to design with and the bottom of the header was ½” higher than the bottom of the pan. These oil pans are made for easy access to the oil filter. They also have a kick out sump which the header has plenty of room for. Measuring from the side of a stock oil pan we have 4” of room on the driver side and on the passenger side we have 2 ¼” at mid pan and 3” at the bottom of the pan. If your oil pan has a driver side pan kicks out under the filter it will cause the filter to be trapped. The Milodon #30951 and #30956 and Moroso #20408 oil pans will make oil filter access easy. This header requires a Nippondenso style starter, we used a Power Master #9540 for our design. A Power Master #9500 and a #9526 as well as a CVR #5323 starter will also fit. This header will not fit a Hitachi style mini starter or large GM stock starter.
The steering column is the closest thing to the header with this chassis, but we will clear it. And still have good access the spark plugs. The header is also designed for clutch linkage and a power brake booster. If you are using a Lakewood type scatter shield you will have to slightly trim the outer edge of it under the starter area for header clearance.
This header will not fit factory type column shifter linkage, but you can keep your column shifter if you get aftermarket linkage from Lokar or I Did It.
Any floor shifter is OK. We offer the Power Master #9540 starters.
We have included a drawing that shows measurements of the correct motor mounts and frame stands so you can see if you have the correct mounts. The motor must be in the stock position.
You can use Prothane #7-504 poly engine mounts or Moroso #62530 solid engine mounts.
You can buy the correct frame stands if needed from Origional Parts Group, their part number is #CH20013.
This header requires a Power Master #9540 or #9500 starter, or a CVR #5323 starter.

Header installation: Pro-Tour Style
Passenger side: remove the starter and spark plugs, install the header from the bottom. With the header in place but not bolted to the head reinstall the starter, then bolt the header in place. If you have a scatter shield bell housing you will have to raise the engine to install the passenger side header.
Driver side: remove the clutch linkage, oil filter, spark plugs and the long bolt that holds the motor mount to the frame stand. You may have to raise the engine about 1” to get the header past the steering column. Install the driver side header from the bottom. When you let the engine back down be sure that engine has centered itself on the frame stands.
Refer to the header installation tip’s page for additional information.
Header Installation: Race Style
The race style header has single tubes and slip on collectors.
Driver Side: you do not have to raise the engine to install the race header, but you will have to remove clutch linkage. Install all tubes from the bottom.
Install #1 tube and only start the header bolts only enough to hold tube in place.
Then install tubes #3, #5, #7 only “snug” the header bolts do not tighten.
Next install the collector that has one of the mounting tabs stamped with a “L”.
One of the mounting tabs on the tubes has a “L” stamped tab, those 2 “L” tabs have to go together. With the collector installed and bolted to the tubes, go back and tighten header bolts. Be sure to read the installation tip’s page before installing the headers.
Passenger Side: remove the starter.
Install #2 (front tube) start one front header bolt only, just enough to hold the tube.
Install #4 (second tube), start one front header bolt only.
Next install the starter, then install the second header bolts in both front tubes, snug only.
Install #8 (rear tube) from the bottom, start both header bolts.
Install #6 (third tube) from the top, start both header bolts. Snug all header bolts.
Now install the collector same sequence as the driver side, the passenger collector will have a “R” stamped on one of the tabs.
Be sure to read our (Header Installation Tips) page before installing your new Lemons Headers, it will make the installation go easier and save you time.
