Okay guys i need your guys input on some heads im thinking about getting for my 98 formula they are the 317 heads. Since Iam doing a head swap iam also going to put a new cam in these are the cam Specs 235/240 .597/.592 LSA 112. I hear i have to mill the 317 heads down to get them to flow like the 243 heads if so how much before the valves hitting the pistons? Or can i just bolt the 317 heads without getting them mill down?

if ur putting a turbo on it then put the 317 on there if not stay with 243, with that cam it dosent sound like it

if you dont mill the 317s they will lower your compression. skip them if your not going FI or i guess if you already have them just run a smaller headgasket
