Small Block Head Flow Chart

Here is some numbers from some EQ heads that I bought through my local machine shop in Winnipeg. The owner let me come in on a Saturday and do some clean up on the bowls first and then do a bit of porting under his guidance. The valves are long stem LS Chevy 2.02/1.60 that they had on the shelf.
Basically the heads are similar to IMM EQs. I would like to buy a set of bare aluminum heads in the future and try a more in depth porting job.
