I'll admit I'm one of those who ordered a pair of the smallblock heads. I'm also very aware that I might/will have to do work/spend more money/time on these heads.
I will disassemble them completely before use and will correct any issues I might find.
But for me, the heads will end up on a daily driven car with mild performance. No 'racing' camshaft with matching springrates or anything.

I have been eyeballing (your findings on) the Sidewinder SB-heads for a while and am really interested in them. But the total costs on my doorstep didn't jive with the purpose of the engine they would end up on.

Also, and it's not that I don't trust the judgement of the pro enginebuilders over here ofcourse, but where are all those pics/threads/experiences of peeps who bought these cheap heads and where valves/guides or anything else has failed?
