Thread: 496 Head/Cam Advice?

Thanks for responding! I have looked at the 320cc Pro Comp heads. I know everyone says they suck but the price is cheaper than having all the work done to my old heads. Theres also a guy in Indianapolis selling 088 square port heads for gen v but I dont know if you can use them on a gen iv?

The 320 cc heads are to large.
I would look at the World Merlin II's cast iron head with a 269 cc port volume.
If you shop around you should be able to buy them for around $1,400.
No matter what you do keep the port volume at or less then 290 cc.

A novice question. Are the Merlin 269 oval any better than a well prepped set of 781's? I was under the impression from another member on here that the 781's with gasket match and proper port work, llarger vavles etc will flow just as well as Merlin cast iro 269 ovals..just a question?
