my pi heads keep shooting sparkplugs ! do the trick flow heads have a better design?

 

yes their design is to prevent that from happening.

 

yes their design is to prevent that from happening. see artical muscule mustangs @ fast fords nov. issue page 84. they discuss all specs on their new head.

 

Anyone seen any NA before/after dyno numbers with these heads!?

I know that Fox Lake is sellign these ported for a pretty hefty price....they really worth the money!?

 

Depends on how much power your trying to make. Remember, in your case being a blower app. the more money you spend getting the engine itself to produce power, the less boost you have to run to get to your goal. If your goals are 400-500hp, no big deal, but if your looking for something like 750-800, that could be the difference between running being able to run pump gas or having to step up to race fuel.

 

Buy cobra heads they dont shoot plugs as often and they can be found on craigslit cheap. 2v <4v

 

theres alot more you need than just heads... if it was a cheap easy swapover there wouldnt be any 2v's on the road.

 

Get Timeserts installed on all eight cylinders, much cheaper than either option listed above and never pop a plug again.

 

not true iv had a time-sert blow out!

 

I wish I had the money for new heads. Now you have me questioning whether I should buy a blower or new heads and cams.
