No flow testing.
Based on RallyBob's testing it's the exh side that needs the work.
That's fer sure!
These just got a lil pocket porting, near valves, w/ most actual porting on exh side. Mostly since I'm also not sure if I'm gonna run regrind cams in place of OE ones.
You just can't get the dogleg good and I'd wanna know how thick the heads were before hoggin them out.
If I was gonna try to max these out I'd definitely get them "extrude honed".
Injectors goin out for clean and cal this comin week.
Still waiting on pricing for shortblock rebuild.

Here's dynomatt or RallyBob's?? info-
Don't know if this interests anyone, but I recently flowed a bone-stock EG33 SVX head for a friend of mine.
It was done on my Superflow 110 flowbench, measured at 10" of water.

Intake flow:
.100" - 49 cfm
.150" - 76 cfm
.200" - 101.5 cfm
.250" - 125.5 cfm
.300" - 146 cfm
.350" - 164 cfm
.400" - 166.5 cfm
.425" - 167.75 cfm
.450" - 167.75 cfm
.475" - 168 cfm

Exhaust flow:
.100" - 44 cfm
.150" - 62 cfm
.200" - 79 cfm
.250" - 92.5 cfm
.300" - 99.5 cfm
.350" - 104 cfm
.400" - 107 cfm
.425" - 109 cfm
.450" - 109 cfm
.475" - 110 cfm

You'll note the intake ports really seem to like valve lift, whereas the exhaust ports are not so good at higher lifts. Note the massive jump in intake airflow from .250" to .400" valve lift. Exhaust flow proportion is a bit low, so that seems to be where development might make the best gains in HP.

To convert my numbers to the common '28" of water' figure, multiply these numbers by 1.67. To convert my numbers to 25", multiply by 1.54.
