sounds like a good setup. Woody knows his stuff.

My only criticism is the heads. The RHS heads are ok but the engine would make more power with either TFS-AFR heads in the 205cc range. Anyway woody is very good and sounds like it will make some power.

Depending on what's done to them they can work . my buddy had rhs on his old ultra motor . been 4.80-4.90 to the 1/8

I do agree on the heads and that's next year's project.... Just don't have the funds this year to replace them.

RHS heads are complete garbage. If you have them, sell them. If you dont have them yet... buy something else.

 

[twolo4u2c2]

I don't think there garbage and worked well on my 347 putting out close to 400 hp. They have there place just like anything else.

I had a set of RHS heads back in 2008/2009. I had nothing but problems with them. The coolant ports didnt line up, I could never get my valvetrain lined up properly. They tried telling me I needed Chevy rocker arms (in my ford). After I ran into problem after problem with them, I took them off and went to a machine shop. Turns out, my heads were no good. Defective right from Comp. The rocker holes were not drilled correctly into the heads, the rocker trunions were not machined properly.. etc etc.

I sent them back to Comp, and after they had them for two months, followed by several heated phone calls, they finally sent me a set of 200cc castings.

yep, bare castings.

Then they took the valves and springs out of my old 180's and sent them to me in a box! So even though I bought complete assembled heads from Comp directly, I had to bring them to a machine shop to have them assembled.

So instead, I put the valves and springs in the heads, listed them as "need to have valve job done at a machine shop" on ebay... and sold them.




Ill never run RHS again.

Sorry to hear about your trouble with RHS, luckly I have had no issues like that.

I spent over a year looking/researching heads before purchasing some TFS 11r 205 heads. Like I stated the RHS heads are a descent head. I just believe tfs and afr offer a superior product. Now if you were looking for a complete high end head I suggest you go to flowtech inductions website and check out some of Ed's tfs high ports. Probably overkill on a street engine but if you were going to run more cam and were going for over 600hp that's the direction I would go.

Thanks for the suggestion on heads.
