I been reading & reading and cant seem get the Idea. I have a genv 454 with 27cc dome pistons, roller comp camp 273 grind with intake at 224 & exhaust 236 @ .50 with a 113 slope, vale lift .537 & 547. I want aluminum heads to clear the pistons. But all the reading about runners , ports etc is kicking my ***. Basically I want a daily driver with torque. Im looking to spend around 900per head if that helps. Weww I had to get all this is out man , I need help.

Or if you can swing the extra and deal with the 3/8 raised exhaust ports.

Thanks Mako! The 115ccs are good enough for the dome? & valve clearance?

What heads do you have on it now?

Alfuego

It doesn't have any. I was a short block only.

Sure should be, you should always check but sub .550 lift in a big block should never be an issue with any combination. Compression and DCR will be fine also.

It looks like im getting Brodix race rices. One thing though,do u guys think I should have them looked at after I get them? Or redo the valve job.?

I bought my Race-Rites from D&F Performance.
They checked the spring clearance and even modified them for the ½'' temperature sensor. They also fitted the exhaust valves with seals.
I got them with the CNC chamber option.
