Thanks for the info!
Not trying to raise anyones blood pressure here,if by me asking questions you are offened,I appologise.

Me personnally ,I would never install a 1.94" intake valve in the small chamber head.

We found out quickly the cfm loss was too much. Chamber shrouding was too much,I I wanted compression,& opening up the chamber was not going to help my quest for high compression.

So we went w/a smaller size intake valve.

We were getting more flow useing a 1.85" valve over a 1.94"

As far as me thinking smaller chamber head flows more,,,not sure what you are referring to?

Actually just the opposite most times.

BBC small chamber bath tub heads are almost the worst flowing BBC head other than smog round port heads,not oval.

We had to open up my already large chamber head to get more CFM out of it.:a couple pics



As far as cylinder head flow & actual real time street/track differences & comparision,I have done many.

I have flow tested pretty decent 6 cyl cylinder heads & work absoultly horrible on the street or track.

It's not always about what flows the best to what will work the best on the street. Sometimes,they just do not go hand in hand
;-)

Keep up the good work!
