Wow what a good thread. Hot rod 101 is the heads. Every one that has anything to do with hot rods finds that out pretty fast but not always the nitty gritty thats devised from. I've looked at several head porters ads lots of times. Wondering what is or is not hype and what really counts.

We are all aware too that the last few horses and foot pounds are what is the most expensive to get. Even then will the car actually be faster?
I'm sure that every one has seen or heard stories about racers who have found out after using some how zuit suit cam or part that a run of the mill part that been around for ever is still actually faster. Your dollars lighter.

Its common knowledge too that people can really get going on over a new part of process only to deciede later on thats its only so so. Now this is showing us what is really going on in the continuing story of head modifications and what we can realistically expect for our cash out lay.

Ultimately a lot of it is going to be the experience with a set of heads with that porter has.
