I have 2 very nice used 3R heads in stock. $995 ea

From the land of the ignorant, what are 3r heads

blown 87

They are the third revision of the four valve head, came out in 88 I think, they are the thick deck heads that need the longer bolts, good stuff.

I think they stayed until the GTS came out, those are 4R heads and have steam holes.

None of this is gospel from me.

These .4R heads that I have still needed to have the extra cooling passages drilled:

RFJ

Thank you Greg, Ray- a little less ignorant.

RFJ

One more question, would 3r heads fit 85 euro block?Ray

James Bailey

The normal 5 liter hybrid has 16 valve heads on a 32 valve block.....so 32 valve heads on a 16 valve block ? stud spacing is the same might need different length on a few. Plus pistons need valve reliefs to match the valve layout

I think you end up with compression too high for pump gas, and the intakes don't swap back and forth do they?

RFJ

Mr James Bailey, thank you much. It seems GB had talked of being able to notch pistons while still in the car. should do rings and bearings though i guess. Ray

RFJ

So then i would have to change pistons as well, not sounding so good. thank you Ray

Are these bare heads Mark ?

Mark Anderson

No they are complete with valves and springs. I can even include a set of cams at that price.

John Speake

That's a great deal, Mark ! C'mon people, buy !

blown 87

For a set of R3 heads with cams that is a very good deal for some one who needs them.
