Broke down and ordered a set of High ports from Jeff. Goal is to get as close to 700hp on pump gas with stock block 455 .060 over. Jeff told me the as cast High ports will be good enough to reach my goal. The as cast ports are 1.20 x 2.30, my victor intake has 1.20 x 2.40 ports. Talking with Jeff there is no problem opening the heads up to my intake as long as I make a long transition. Just out of curiosity I asked the port dimensions on the 365 cfm head, 1.20 x 2.40.
While I am using the burr to open up the port .100 is there anything I should do to the stock head to increase the flow a little?
The 365 cfm head is a little to much for what I need. Would like about 340cfm.
This is going to be a high effort pump gas combo. Will have 11-1 compression and jeff agrees that that will work with 93 octane with the cam I have.

Want to run 10.00 in the summer at 3200 lbs.
Old combo had 692hp (calculated from et) with 11.75 compression and Old E-heads that flow 330.
