afr is the only aftermarket head i will ever buy just my 2 cents

 

I milled my Trickflow heads down to around stock chamber volume. If you decide to go that route, just tell whoever is porting your hgeads to mill them. You may have to mill your intake to fix the difference though.

 

BTW how good are the Edelbrock heads? I have been hearing horrible stories about how they just perform a little bit better then our stock heads.


It seems the other guys answered the question for me.

 

you will have to not may lol

plus when i got a set in 2 years ago and did a out of box test the edelbrocks were a waste the trick flows about a stage 2 lt4 portjob and the afr were in a class of there own and killed them both

 

Just had a set of LT1s ported and Used Manley Pro Flo valves new.They touched 300 and I know this guy very well. HE does alot of NHRA cars.4 World Championships under his belt.He helped me set 13 National Records over the years.
The #s are real and he's the real deal

well i was doing a lil home work trying to see which way to go ...it looks like my best bet for the 1200.00 i have to spend is to use my stock heads and have them ported and new rr and springs and such done to it.....

 

That's what I would do. The stock casting is pretty good all by itself (for a production head). It's not really rocket science on these heads. The porting areas are pretty obvious for both heads alum and iron. The aluminum head needs quite a bit taken out just past the intake opening on the roof, and in the chamber, the exhaust valve can be unshrouded a whole bunch. Getting each port to flow the same is the trick. Don't go crazy on valve sizes either. I would go with 2.00/1.56 and keep the factory seats.
