Yes I consider porting my stock head but the cost was 975. The machine shop stated that after market head would flow better than any work stock heads. AFR told me I would probably get the heads in JUlY or Aug due to back log. Should I use different rockers? Can use my stock lifters? My LT1 is a 1995 builded in August and I'm not sure if it's vented. How can you tell if it's vented? What's the cost of the 12 bolt? If I change the cam to 114LSA do I lose anything. I talk to Summit, they said with the items I putting on it should work. The TF where design for a 383 or SC which I will get next year. But with the 3000 stall and 3.73 gear Summit said it should produce good number. What do you think?
