    Default How to Install TA Performace Rover Heads on a 300 Engine

    We've been getting a few people calling asking if they can put our new Rover heads onto their 300 engine and how to do it. I know you guys have been talking about it for some time and I got the feel that you guys came to a general conclusion of what needs to be done. Would someone be willing to share what needs to be done to install our new Rover heads onto a 300? Maybe this can get stickied for reference if we can get it listed thorough enough

    I remember seeing a lot of talk but it was all in various threads, I thought it'd be helpful if we had one thread dedicated to it. And the heads are currently being casted so we're *hopefully* looking at being able to machining them within 2 months.

    I think they require a custom intake manifold.

    That would be the big item, same thing for the 340, although it might be feasible to do it with spacers if a large enough BOPR (215/Rover) intake were available. Current runner sizes aren't likely to favor the TA ports. An IR intake is an option, but an expensive one and not easy to find. An iron intake should be usable, but heavy of course. Also spacers elevate the carb flange.

    Head gaskets are another possible issue. They should work OK with the 300 gaskets (or 340,350) but will not work with the BOPR gaskets, as they will not seal the upper water passages.

    Other than that I think the standard issues apply like chamber volume/compression, pushrod length and geometry, and then there is the exhaust port. Rover sells some extremely good stainless MLS exhaust gasket pairs. I've used them, they seal perfectly, and are re-usable because the stainless does not burn out or take a set. They always seal because of the spring beads around the port openings. But they are too small for the 300 sized ports and obviously would be too small for the TA ports. A bit expensive but well worth the money, if TA could offer that type of a gasket it would be an instant success.

    The ports cast into the head are the same size as a stock rover head (and they flow 280 cfm at that) so that intake manifolds will bolt on and work, but they have enough material in them that they can be opened up to the size of a V6.

    So spacers for the intake side might be appropriate, I think something about 9/16" or 5/8" thick is needed just going from memory. About 1-3/16" for the 340 or 350. That's if there is a BOPR intake that will flow 280.

    Are the exhaust ports Rover sized? I'm a little surprised by that as the ports on the aluminum 300 heads are considerably larger.

    So, a 300 can have the ports opened up and use a stock cast iron 1965 300 4bbl intake (If you can find one). Or... a 64 alloy intake. 340 can use a stock 66-67 4bbl intake.. or... a P76 Wilpower single plane intake with spacers.

    OK....
