Seems like it could be better. How does this compare on the scale of good flowing heads?

Untengijutsu

what lift ?

B18CR head, Portflow job
At .500 and 28''

288.4CFM intake, 202.4CFM exhaust
Uncut guides

I trully like this head and the servies I got from Tom and Laskey Racing, it putted good power too, see sig.

.500", 288" & 202" is impressive. Was that with stock valves?

Every flowbench reads a little different from one another even though they are/should be calibrated. Most "ported" heads flow around 280ish CFM intake though so take that for what its worth. If it can flow around there you'll be able to make good power from it. Obviously the shops with more experience and technology would be able to get more flow than 280 but 280 would be a decent flow number to base off of.

Stock size, off the shelf supertech dished valves.
I wanted to keep the guide uncut, Mike at Laskey was also impressed by the number for this job.

I posted in another thread but I have my head I hand ported flowing right at 290/205. It took ALOT of time and fine tuning, but it will be worth it when I finally get to slap it on.
Here is a pic

Really nice. I'm going to give them a hard time. I picked it up to check v2v clearances & when I take it back I'll say they can finish porting it now.

Was any work done to the chambers?

This is my gsr head before and after with stock valves.

Sorry for the pic being sideways. I don't understand why it rotated like that.

Were you asking me or the OP?

JBerta that flow chart looks nice for a street head

Do you have a flow chart for the head? For instance a stock itr head usually flows around 260-265 stock depending on where it was tested at.. cfm is just capability really, the numbers in my opinion are just numbers if one doesnt have the support mods to use that cfm number. Your head might be a low/mid lift monster and you not even know it :-D.
