i am NO Ed/Curtis when it comes to the head combo's etc...but i am an experienced past alcohol blown injected motor guy..both small block and Big block, have also owned blown carb small block's...
a pic was posted of one of my past blown alters in the general section under (roadsters)
Head porting will most definetly
help the blower application..Now there are different degree's of blown motors..the street driven small block 144 or big block chevy 177 or street 871/671...At minor levels of boost would not NOT REQUIRE head porting to see the benefits of the forced induction..but even the minor street motors would benefit from a very mild pocket,gasket matched port work...IF ANYTHING LESS HEAT BUILD UP.....i have heard people say PORT WORK is not needed on forced induction but i have learned these are the same people that are too tight to spend the $$ or cannot afford to spend $$ ( which is ok)..or the type of person that never washes their car or changes the oil ( ever)...So please consider the source when you hear comments like that and see what these people have( how their stuff runs) and what have accomplished in the sport.
....its also the same people that show up at the track and running 1 second slower than you but for some reason they want to tell you how to tune your car....i deal with that more then you know...LOL
remember with any blower set up..the quicker you pack it in (air) you must get it out just as Fast if not faster.
So port work is BIG BONUS and almost a requirment on some higher end blown stuff where HIGH BOOST LEVELS are invloved
think of it this way...would you like to try to breath thru a "Mcdonald's straw or a 2 inch pipe ?
This is my KISS theory along with some past experience.
also depending on your Boost levels..have the blocked O-RINGED AND/ or reciever grooves cut in the heads.....or at minimum get you some FEL-PRO MLS COMETIC head gaskets and be sure to stud the heads and you should be just fine
thanks
