My home inspection of Speedmaster heads

If anyone is interested, there is a decent article on porting the chamber in the March 2020 Car Craft magazine I just received. They are working on an aluminum LS head but same theory applies to Mopar heads. They go through un-shrouding the intake and exhaust valves on the chamber side and give the before and after flow numbers for just this mod. Went through it briefly but it looks like they get 10-17cfm on both the intake and exhaust between .200-.400" lift. The exhaust gives a little improvement above .400 but intake looks to be done. I think PBR is getting ready or has already done this to his heads. Article has good step by step instructions and pictures that just about anyone should be able to follow. Should be on the news stands soon I would think.
