Porting 241's
My heads are getting closer to being finished. They are being ported by a local shop (friend of mine), still a little left to do on them and then the valve and seat work. I think the numbers are looking really good so far. Im running an LS6 intake, G5X3 cam, TD's and QTP LT's, should be fun. Stock block though What do you guys think? If I remember correctly stock flow was 253 at .5, 252 at .55, and 249 at .6. I'll have to dig up that sheet
