360 head trip

I'm getting this thread off track here, but...


From 165-200.cc
Trying to get a port in the 165-170 cc to flow in the 255-260cfm range.

keep in mind these are epoxy filled. trying to get ride of all the dead spots and not go turbulent.

I have had the stock port(read no epoxy and a 2.02 valve)go 260 but then had to play with all the dead air on the floor,....yeah it don't like It!

fill the floor, raise the port entrance, widen ssr, raise roof and then fill in apex of the short turn for a better radius for the air to turn on ......and now it to "small." csa......
Over and over and over again:violent1:
