SBC COMPLETE HEADS 245 INT VOL80CC CHAMBERS STD EXH HT

Description

AFR is proud to introduce
our new 245 NPP (no pushrod
pinch); best suited for max
effort applications, but
larger displacement 427+ pump
gas engines could consider
this head as well. This
exciting product represents
our best flowing 23° SBC
head to date and while flow
numbers may reflect a very
good 18° head of the
past, this head is still a
conventional direct bolt on
non-raised runner intake port
configuration. It will drop
on your 23° short block
as easily as our 227 or 235
SBC product and in fact
shares identical valve
centerlines and rocker stud
locations to both of those
heads. However, unlike the
227 and 235 heads, this
product will not accept stud
mount style rockers and a
shaft mount rocker system
with a .180 offset intake
lifter is required. Larger
diameter 3/8″ pushrods fit
without additional
clearancing. This isprimarily
due to the fact we enlarged
and widened the pushrod pinch
removing that checkpoint in
the entrance of the intake
allowing us to design a port
with a more direct shot at
the back of the valve that
also has a more consistent
cross sectional area and
velocity profile. In
addition, this head comes
standard with a 3/4 inch
deck, 2.125 intake and 1.600
exhaust. The exhaust port and
bolt pattern are raised .250
over GM L98 head(see
footnotes here), this rarely
affects header or chassis
fitment. If you are unsure if
this is the right AFR head
for you, we encourage you to
contact us directly to
discuss your combination.
