well just want to know is there anybody runing the MTI stg2 R heads with this size motor

 

You can but it is recomended to run stage III big bore chambers instead. Unless you are at very high compression (like 12.5:1 +), you would be leaving lots of power on the table.
And if you did so, you better pay attention to your cam grind for DCR values.

 

thank's
so stg 3 here we go

 

Sal,

Those heads could be opened up to get the job done. It'll cost a bit, but they will work. Like Predator stated the upgrade will be well worth the $$. You could always sell them and buy a set more appropriate for your big bore plans.

Those are really good heads for the 3.90 bore/smaller cube guys. There is a market for them.

Good luck to ya buddy!!!

 

thank's James
well I'm getting ready for the big buy
