will I need to flycut with new heads?

question about heads and flycutting. mods in sig. stock ls6 with btr 4 cam. runs great. Im guessing my PTV is really close as it is right now. If I send my heads off to get worked on, how much do they typically take off the bottom to level them....or do they?

Sent some emails to TSP, AI, TEA, BTR, ect, but most havnt emailed back yet and/or no help. Tony messaged me back and said to call him, just havnt had time yet, stuck at work for the next 4 days

Im leaning towards the AI 226cc 243's, will I still be able to run my BTR 4?

Let me know what I should do. Thanks

I know when tea ports them the cc goes up so you need to mil to lower. When i emailed AI he said after porting and 60 cc heads the biggest i could go without fly cutting is 230/238 113 cam .605 lift. When i talked to BTR they told me stage 1 tea 243 heads milled .030 (which according to tea comes out to 63cc) i could run the BTR stage 4 cam which is 235/242 .621 .592 111+3.

TEA said no milling, Mamo said I need to call, Im still working 13hr shifts until tomorrow, Texas speed calculated .015 MAX, and AI said GUESSING .012 to .018. AI said to ask BTR; BTR said to ask AI.
