Now that you've talked to him and he shared his 'logic' (which is completely off base and shows he knows nothing about flatheads). His logic on the press-in guides is all wrong - and he even did a poor job at that - as the spring heights/pressures are all over the place. Even if he knew what to do, he got into a big hurry and made bad decisions - he should have just stopped and acquired the right guides (would have taken a day from Speedway).

You should be having the whole engine taken apart, inspected, fixed and re-assembled by somebody who knows what he is doing with flatheads and has the equipment to do the job.

I wouldn't trust anything on this engine - so why take chances after all the money you've spent. If you need anything more, feel free to PM me - be happy to talk to you.
