360 head porting for big power (500HP ?)
Pushrod pinch is always a bug-bear with factory iron heads!
It can be fixed with ali-heads and clever reworking of the port entrance.
Then finding a set off decent offset rockers is the next problem.
But as we all now know its worth up to 100HP...:thumbsup:
From this angle we can plainly see how much port is blocked off...:BangHead::BangHead::BangHead:
