So intakes alone add 20+, if including exhaust cams then it's a total of 25, correct? |

Re: Some "Dynomite" Heads!
Decided to take a few hours and finish up the port work on the intake so I can send it off to powder. I went a little bigger than usual on this intake since the ported heads will be able to take advantage of some extra flow. Here are a few pics:

Re: Some "Dynomite" Heads!
Oops! Guess I will need a new one of these. [/QUOTE]I will give away my one and only secret porting tip....I don't trim the 1.5". I spray it in alittle WD40 put it in the opening of the port and spin it up slowly, and you end up with perfectly round ports.(At the gasket surface) PS: Cams should be complete next week sometime
