what ex manifold

I perused the IMCA hobby stock rules & see the italized note that schoenfeld 4485-20 headers are now allowed. I talked to one guy there at schoenfeld & he said the part # for the EQ heads version is 4485eq-20 but they are refusing to sell them because of no fit. I called back later & got another guy & he said they are available but there are several caveats: you must run a robbmcperformance mini starter for clearance & do some grinding on the bellhousing. the starter is $390 + $330 for the headers. I do use a chrysler mini starter (not sure what it is off of but it is very small). I wouldn't imagine that the robbMC starter could be much smaller. I worry about the kickdown linkage/pivot on the side of the trans. If I had to ditch that could I just wire the kickdown lever all the way back? this is where I am at so far.
I wonder if you could get a set of chevy headers from speedway and carefully without scratching them up hold them in place without bolting them to see if they will clear your starter. You should be able to return them if you don't scratch them up.
