As some have seen here I had a SFT tool steel cam & lifter problem,so I decided to go through the engine & clean it all out & new bearings & rings, going roller cam, so I took the heads apart & found that I had some guide wear also, replace all the guides & took the heads to get a nice STEET 3 angle valve job done & set up new springs,then I ended up in the Hospital Christmas eve with REALLY bad chest & rt side pain, they found gall stones & plugged up ducts from stones, they did 2 surgeries & the gallbladder is GONE spent 5 days in the Hospital, while I was there the wife pick up my cyl heads for me, so now on Jan 11 I am finally starting to feel a little better & decided to fire up my old, dinosaur, liquid filed gauge, purple shaft design flow bench, 1st i calibrated it, ran it & re calibrated it again, I wanted to check the flow after the work done, not great heads but they work good for my daily driver on a 512 LDeck, I am posting before I did any port work & after ported & the current 3 angle VJ, sorry for the long post but I have been stuck in the house for weeks LOL

Thanks Dwayne for the rocker arm help & B3 racing for the geometry correction kit.

Glad to hear you're back at it!!

MW port openings?
(Edit-oops, I see you said it is MW)

What's the width at the pinch?

1.350

Wow..... Pretty spacious!!

yes it is , large lazy port, I should have used a different head but I was in to deep to start over,, headers,rack & pinion, angle plugs , the car ran fair before with the small SFT 248@.050, new cam 255,258 @ .050 roller, gonna need more converter.

Put a cam in that puppy..............

Ever CC any of the runners?

Still using a 2.14 valve?

yes on the valve, it would like a larger valve, BUT, the seats would have to be changed

Sorry I missed the cc part, no I have not, all my ccing tools are gone after I got sick in 2011. with a 2.14 valve, what size do you think the throat should be ?

Depends on the lift of the cam....... But with from what I've seen with the RPM heads, and all the variants and copies...... the throat is too big(92%+)for the 2.14 valve as they come OOTB.

Then you have the opposite end of the spectrum with the std port Victor heads where the bowl diameter(even with the guide) is about .300+ smaller(about 1.750) than it should be.
The RPM bowls are close to 2.050 ootb.
Doesn't make much sense that the "race" head has a bowl that's .300 smaller than the street head..... Especially considering the race head uses an intake valve that has a .060 larger diameter.

For comparison, the TF240 bowl diameter is the same size as the valve....... 2.190.

Thanks for the info Dwayne !!!
