Re: Bowl Blending? (T-Top Tom 1)
Machining and casting immediately behind the valve and around the guides is very rough and causes a lot of turbulance and restrictions. Bowl blending smooths this area immediately behind the valve and into the radius (turn) and is the biggest bang for the buck in head work. This includes cleaning up any casting slag or irregularities, smoothing to the radius and smoothing around any machine work and may include around the valve guide depending on who is doing the work.

Re: Bowl Blending? (blunsford)
thats got it :thumbs: :iagree: i've done a bunch of bowl jobs even on trash
smog heads. it's cheap power, the only head i've done that a little pocket work really wasn't felt was a 2.2 chry. turbo, i pulled it back off and staighted the ports a little and matched the intake to the head :thumbs:
then you could tell something wasn't stock, :thumbs:

Re: Bowl Blending? (pillowmeto)
The vortec heads are excellent right out of the box. They are a high swirl design. If you have anyone do port work to them make sure they are familular with the vortec design. If you use convention porting techniques with a vortec head you will decrease the flow rather than increase it.

:iagree: the intake's are the strong part of the vortec's the ex. needs a little
more work , done 2 sets 1 for a S.Burb the other for a 4x4 both did great :thumbs: i word the intake on the outside of the bowl mostly to increase the tumble and not hurt the swirl on the ex. i worked 360 deg. of
the pocket. on the burb. it didn't even have headers and picked up 2 mpg
on highway. ( it was my work truck) had intake leak, asked boss if i could pull
heads to inspeck :blueangel: he said ok i came in on sat ported,mon. put back together :thumbs: :thumbs:
