Porting LS 862 heads 215cc
Starting another set of 862 heads:
Upgrading to 2.00”/1.55” valves and porting them to 215cc/82cc ports.
Chamber will be modified to unshroud the intake valve to improve flow.
All roughness or casting irregularities in the chambers will be smoothed.
Honestly we ended up not needing 61cc chambers,I’m hoping when I’m done I can get them to 63cc+ to help control compression. I’ll have to explain later why...😉
