I started and ran my '83 without issue a ton of times with headers (so no heat riser) and a working choke in single digit temps. You get heat from the exhaust crossover under the carb anyways. The stock manifolds are already restrictive enough...</div></div>

Good enough -- just takes a skoshi longer for the manifold to heat up. Another issue is when using stock exhaust head pipes, because the heat riser (about 2&quot; thick) was removed, now the pipe may be too close to the floor pan ... assembly will show what the clearance is ... TAZ
