Thanks. The car it’s intended for is for use with 1-3/4 headers as well. Currently it’s being used with the typical crappy 1-5/8 header.
What rocker ratio are you running and what cylinder head? Ported?
Rockers are PRW stainless 1.6. The heads are lightly used ProMAXX 171 and haven’t been touched far as I know. I’ve measured for one of B3’s correction kits and need to get it ordered.
