Hi everyone.

I have a few questions.
I am getting a 6bolt 1g motor swapped into my 95tsi i am going full rebuild green turbo,crower rods, je pistons, bla bla bla.

I am also putting on the 1g head and want to know what kind of flow numbers I need to see on the flow bench ?..I am havving my friend who is a renowned off shore boat builder do the heads...his first mitsu.. He is a very talented buider and has built numorous motors for sportsman oval track, super late model open wheel cars and offshore boats APBA, LSCORA, ARCA, Winston Cup, SCCA, HRA, NHRA etc. so he knows allot of tricks I just want a baseline for a good high flowing 1g head..the car is aimed at low 11's high 10's

pics of a modded head would be appreciated ..

Very hard to say with the many factors that play in to this. I would GUESS that flow numbers near the 200CFM range per chamber would be very nice but info like this people ( just like my self ) are not going to just give away. Shoot for numbers AROUND that and see what you get. I tossed to many head to give away info like that for free. I have what "I" like to see with the combo of motors that I build. If he is that good he won't even have to ask you, many basic rules apply to porting, he should know them if he is that good but remember that this is NOT a off shore motor that at best sees 5-5500K RPM's this is about top end HP not down low torque. make sure he knows what your looking for out of the motor. ( RPM's and Boost levels )

Even a stock 1G head is good for 11's.

There's not a whole lot more you *have* to do to get it running lower.

maybe a decent cleanup (of material), polish, oversized valves...
