milling B/RB heads

send your 452's to a head porter who knows what he is doing!!!
dwayne porter(fast68plymouth from MOPARTS) PORTED RACING HEADS in vt. ports BIGBLOCK mopar heads...he can get your 452's to flow really well!!!

you need to find out how much comp. you have and then he can tell you what,if any, that you can mill off....your gonna want to run between 10:1- 11:1 comp. with the .509 cam.

if it were me ,id put on a GOOD single plane intake like the M-1

my uncle has a 68 roadrunner with a 440,.030,STOCK crank and rods,TRW with around 10:1 comp.,915's with 2.14/1.88,holley strip dom. and a 850dp
727 10" 3800 dynamic,3: exhaust and 4:56's and with LITTLE tuning it went 12.40@106
