** NEW ** Trick Flow LA cylinder heads introduced at SEMA

Striaght side?

I have no knowledge of this stuff.
 
You still line up the bore with the straight side even when it's too large, so the diff is only a few.

I have never done this, but i have tried different bore sizes with vary little difference........unless it was to small, then the bores, having valve reliefs made a big difference.

Read a thread on another Forum about how those CNC shocker heads can be 20 CFM shy of what's advertised =285 cfm -20=265cfm
Which should not be a surprise, variance that is in reproducing that or should I say duplicating that same CNC on different ports that shifted differently


I think that hits it right on the head!!!! :D
