Tlowe used a sawsall to remove the bosses and my instructions from PES said to use a hammer. Removing the bosses is not high tech.
I donated to the dyno tests. It was a very interesting & productive time here. The problem for me is that by nature the dyno pulls started at near the top end of the rpm range i'm looking at for my truck engine. Nothing above 3,500 rpm is important to me nor is what it takes to get power up there or above. Idle to 2,500 & cruising at 2,000. From what I have seen & read a near stock head, in my case a 194 head, will have adequate flow and removing the bosses will will result in a loss of velocity at the lower end. I'll do some reshaping as shown in pictures Twistedsix sent. If it doesn't work I have other heads. With boost it's probably all different and I'd need expansive pistons. Other than the cam this uses parts I have laying around
