Not sure what to make of that. There is a post from him somewhere here where he mentions that. Back when he was doing a lot of Pontiac stuff he had a 459 CNC program for HPs.
In those days he had that Pro Port pump gas engine near 1000HP, Mikes E heads that made more power than your Barton High Ports with a like build, They went 414cfm, highest I know of and were not even flowed the last 2 times he worked on them.
And that set of High Ports of Giro,s that inspired Mike to go with Marcella High Ports.
Giros had the valves in stock location and Mike told me himself he thought John could get 480cfm with the valves moved around.
Then there were the 502cfm @ .850 lift Tigers he did.
For awhile it sure seemed like one guy had the best Pontiac E head, Pro Port, High Port and Tiger head. All done with welding, no stinking epoxy to leak later.
Not sure I would doubt anything he has done.


Who bought Giros top end with Mikes BOP. And whatever happened to Giro ?
That guy was a blast.
