I will go ahead and do it if you are willing to accept my head
. Just curious to know how long it will take. I will make the payment once the head has been flowed before / after and there are decent gains etc and after I see lots of pics
. Hope this helps you find out the "sweet spot" for these lsj heads man!

Trust me I know, flowbenches are a tuning tool, and nothing more, what really makes me laugh is when people take stock flow numbers and compare them to numbers from a head flowed on another bench, doesn't work like that. As I stated in another thread, percentage increases flowed on the identical bench is the only way to compare gains.
No offense mike, but it seems like you overlooked some key things stated, such as they were unfinished, granted if you were to look at the pictures alone and not read the posts to follow, I can see where that could be assumed. Again, no offense. hell, I've seen a 15 percent increase from taking out the casting roughness alone, the port looks nice and performs decent, it was an experiment that I'm running on my car currently. Plenty of low end torque but seems to lack up top, the others I've done with the same mods as I have, even with a larger pulley pulls away up top, where I think the head holds it back, I've played around with a few port designs, and I don't send out anything that I wouldn't be proud to receive shipped to me.

ok after some conversations (lots of them cause my phone service sucks) ive come to change my offer for anybody interested. i will race port the exhaust side only with some combo clean up instead of a street strip port. i ask that whoever if anybody sends me a head they ill do the port work for free and they pay for the machine work (race valve job and resurface), flow bench and return shipping. if anybody is interested go ahead and pm me. i wanna see what i can do with these lsj exhaust ports as ive gotten 208 cfm out of my l61 ports already.
