guys, keep your eyes open as RHS is back in biz here in memphis. we just sent out a $28,000 order and one more a good bit larger. we arent in full swing of doing the head work, motors and such like back in the day but we are aiming towards this.
i know all this first hand as im in the comp shipping dept.

 

What are you guys talking about. I know three guys here in Nashville running 10+ psi on their LT1 cars. That is just guys that I know and talk to at least a few times a week. Close friends of mine. Two w/ S trim Vortecs and another who WAS running a P600 Procharger. The two vortec guys are hitting around 15 psi. They are both really close to the 9:1 range. 9:1 is good for about 15 psi from guys I have talked to. Get any more than that you need 8.5-9:1 range...

 

is that racing gas?

 

boost and compression is all in the tune.

what about those hondas with 10:1-11.1 running 8-12lbs on stock bottom ends? It is ALL in the tune. Very different engines, same concepts.

 

fuel injection also helps alot!

 

I wonder how these would flow on my 305. I am in need of heads now since something bad happened to my heads .
I am leaning towards the World heads but these heads are really really nice. Whats the opinion on me getting these heads for the 305 sitting in the roc. I do have a set of 416's laying around as well.

 

flow numbers for the trick flow heads, check out this post:

Nice flow numbers but it seems that the 416's might be a better deal for a relativily stock motor. Unless I get the First Injection set up that I want.

 

i want to get these heads and the comp cams xe274. i think they would work really well together in my 305.

 

Yeah I agree. I am thinking about getting them maybe they will come in handy. Just got a new cam A Comp Cams .464/.464 lift. Lets see if it helps any although I will need computer mods now.

 

I know this post is 5 years old, but .... Did anybody ever get these heads? Are they happy with them?
