I had my head shaved for better compression and put the Chevy valves in. It just cost me more money since then I had to use higher octane gas ever since. I wouldn’t recommend it. She won’t need valves since she just had those done. We went over all my costs, leaving out the things I thought she could do herself to save money, and that’s where the $1700 can from. I’m sure there’s things that may have been forgotten, like gaskets and whatnot, but I’m pretty sure she’ll figure it all out. It was in 2014 and I let the shop do some of my work. Not much, but enough to add significant cost. I’d say my total costs were closer $3500 after it was all said and done, without the shop building it. They did do the head tho. We all have seen what Felicity can do and she has already done pretty much everything once, except the pistons and rings. She can handle it. I never rebuilt anything before and didn’t have an FSM and mine is still running great albeit it’s only been around 15K miles put on it since then. If I can do it, she can. Regarding warranties from a shop, will they really honor their work? I suppose if something happens quickly after the build. Not much later. I wouldn’t let someone else do it. That’d take all the fun away...
