Default 5.3 Flow Numbers Are In.

Ok after waiting a month my heads are on there way. They are the 5.3 s2. The heads flowed 298 cfm on the intake and 237cfm on the exhaust @ 600 lift. Would the F-11 be a good match for this? Thanks

My thoughts exactly.Most REAL world Stage 2 LS1 flow numbers are 290-305 with 5.3 heads..and thats plenty for the average build up.The exhaust numbers are great if thats without a pipe!
