Re: Heat Riser/EFE Valve Spacer
I cut out the butterfly in the heatriser on the 305 in my '84 Trans AM. the damn things seize. Not really required. Had a '70 Chevelle L48 engine. Removed the rise because it was seizing.

Re: Heat Riser/EFE Valve Spacer
The purpose I have for one is to fill in the space, my headers are smog legal designed for the valve. I just want the correct size spacer, was able to find them years ago fairly easily for my other smog legal header cars. I could modify one but rather just find a factory spacer first.
