Which head??

[figair]

Can someone please help me here? I have a milled head and my mods consist of:
Riva Head
Blackjack Carb
Lightnd flywheel
Port-polish
and my milled head on a 61x
I believe i am bored 1 over
It's been year's and I forgot, but pretty sure...

My ? being. Should I get a girdled head? If so, which domes do I go with? I can run 100octane. But, do I really need to? I am trying to get a little more pep out of her. Please, any help would be greatly appreciated..
Thanks Eddie

The only reason you would want a girdled head is to keep the cylinder from cracking. Its a good idea to put one on. You only need to run race gas if you're compression is higher then 190lbs, so the question is, what's your compression?

What are you running for a pipe? If you're running the stock pipe then you should put a pipe on it to get some more pep.

My bad.... I meant Riva Pipe-rather than riva Head as I mentioned..
But, thank you for your imput. I just purchased one, so I am stoked and cant wait..

Fix your keyboard dude! :chairfall:



The Riva red pipe is good for all around power but if you're looking for bottom end you'll want a B-pipe with the limited chamber.
