Afew concerns:
1. I overported this in efforts to run without inserts.
2. if I decide to the use the inserts there is a gap between the port opening and the exhaust insert. Would that be worse than running without insert?
3. The scratches/chrome flaking. The chrome flaking is in spec and that is the worst area out of the pair of housings. I can barely catch my finger nail on it but I'm sure its more than .0002" or whatever the spec is.
I'm tempted to use these, would you?
Notes:
This is a half bridge engine with huge ports, 4 port t2 end plates, s5 NA center iron.
I put a stock NA housing with stock insert next to this next to a stock NA housing with t2 insert to be able to see the difference.
