Well i got a sweet deal on some Original Iron Gt40's. They were taken off a lightning and they only had 12k miles on them. I have been trying to get some important info on them to see exactly what i need/want to do to them before i bolt them on. I found this link online but the info does not seem all that accurate?! http://www.themustang-net.com/tech_articles/gt40p.shtml
What size are the Combustion Chambers for real...66.5cc doesnt seem right? I would like to keep my 10:1 compression and i know stock heads are something like 58-59 cc. How much would i need to shave off the gt40's to keep my 10:1? Or can that even be done? Also I already have real nice comp cams springs, new retainers, guideplates, pushrods and CC pro magnum 1.6 rockers. These are all on my current stock heads...will I be able to reuse everything on the gt40s? I will be taking the gt40's to the shop for a 3 angle valve job and to check the straightness and valve guide condition. Is there anything else i need to do or buy ahead of time? How much power should i expect from the upgrade? Mods are in sig..thanks!
