Head games

[7point62fmj]

Ok when I bought my replacement brat for the one that went up in flames:-\, the guy I bought it from gave me a bunch of free parts. He told me that one of the spark plug holes in the current motor had been heli-colied but did not effect the motor. (which it did not)

One of the things he gave me was a set of replacement heads. So My question is. Is it worth it to have these things p&P'ed and decked and rebuilt. I am not expecting any thing all that great just a little more umph would be nice and since there here I figured why not. Also does delta do this kind of work and how much?

Thanks in advance.
