ls2 head compression difference morning
i have a ls2 aluminium block
stock pistons and rods running 0821 heads
i measured the heads at 70cc for cumbustion chambers
now my 241 heads just look like the combustion chamber is smaller
For more performance (higher compression) could i port the 241 heads and have the gass flowed with bigger valves
and run these heads on the 4inch bore of the ls2?
im based in south africa and i dont have access to 243 or any other options

Your better off porting and milling the 821s then spending the money on porting 241s. 821s I wanna say will flow more stock then a ported set if 241s. If you wanna save some $ I'd look at flow numbers to make sure 821s do flow more then a set of ported 241 an if they do or there real close I'd mill the 821s an run them,. you save $.

what amount is safe to mill?
with out running any risk of VTP clearance issues?
