Deck height

I may be wrong when talking machine ( ing ) talk but these two heads are not far from each other...in other words prob. no great advantage to either of them as far as having any kind of gain to save a few bucks cause alot of material has already been removed and paying to have material removed is where I am nearing at this point.

I feel better about using this head I think cause I already paid X dollars to have the other one done and technically it is done ( maybe not done precisely ) and it will be a good spare.

I didn't know that you had them machined flat already. I thought that they were used just taken off an engine and cleaned up (grease/carbon wise).


I would use the second one with the 60 cc chambers, as it was more consistent. The other one will still work on a daily driver, 1 cc won't make a noticeable difference.

I would do any porting first, just in case the seats may get accidentally knicked. It's best to do the porting before the valve job.

Then get the oversize valves installed.


Too bad you're not closer, I know a guy near Detroit that does good porting and valve jobs reasonably. (He gives good head - LOL!)...
