Picture of 340/360 head porting....Mistakes?

I think it would kinda be apples to apples. Shave to get compression(and a bigger quench surface) but lost in some cfm.
Original open chamber set up with potential better pressure recovery but less compression.
Basically the question would be, does making compression made that way, a plus or a neg, in power.
More compression and quench may win out.............or maybe not. sure would be a cool test!

You don't have to give up quench with the OC heads. Remember, rod/stroke ratio changes the size of the chamber. It's a time thing. Higher ratios make the piston hang at TDC longer, therefore, the chamber is smaller, longer with a higher rod ratio.

The higher ratio also affects piston time at BDC which affects exhaust lobe timing. It's like kissing your cousin. Well, not really. I just been wanting to say that. Kinda like Robs $2.00 ***** on Coke. I'm wearing that damn thing out.
