These are the flow numbers on my LT1 heads off a '95 T/A. How do they look? Are they bad, good, average, above average or great? I don't know anything about flow numbers so I'm kinda lost

2.00/1.56 Manley race flow valves
Crower Springs, Chromemoly locks and retainers Good to .580 lift
Comp Cams screw in studs and guide plates
Flow as follows:

No Port attachments

.100 71/62
.200 133/112
.300 187/157
.400 219/185
.500 248/192
.550 258.5/193.5

Thanks guys!

 

Are these my old heads? I sold them to a guy in Saraland with a white T/A.....do they have Killians Porting stamped in the end of the head?

they look really good put a joe o cam in and make some power....

 

i heard he is not grinding cams anymore. is this true.

 

As stated above , I had a set with identical numbers. Put a custom grind Crower cam in 224/228@.050 112 LSA shorty headers 52 Mm throttlebody, 30 lb SVo injectors in a 3700lb stock suspension 94 six speed Z on drag radials went 90 MPH in the 1/8 mile. These heads will make good power with the right cam.

Numbers look pretty good actually. I'd rate them somewhere between a stage I port and a full stage II.

I see your best pass was a 12.39@114, what was the 1/8 mile time and speed on that pass? I never ran mine 1/4 mile with that particular combination.
