My home inspection of Speedmaster heads

PRH said
These RPM heads, and the copies have been around for quite a while now.
Tons of them have been on the dyno.
I don’t ever recall hearing of anyone having to run the timing at 40* to get the most power when using these heads.

I have to chuckle.......a few exposed threads around the plug has people in a tizzy.
But that big fat low flow valve job is a non-issue.

In my defense all I posted was some pics of how the holes are finished on both these heads, and stated that to me it is an attention to detail thing. I wonder why TF does what they do? On first glance it all looks pretty, and for what you pay, they look pretty, with attention to detail that caters to anal guys like me:lol:
